FEATURES

Hybrid SDR Configuration

In add-on to the Narrow band SDR receiver, that boasts overwhelming Basic Functioning, the Hybrid Configuration Digital Processing with Direct Sampling SDR permits inclusion of the superb Real-Fourth dimension Spectrum Scope. *300Hz and 1.2kHz roofing filters (Optional)

Narrow band SDR

Crystal Roofing Filters produce phenomenal Multi-betoken characteristics

The Down Conversion blazon receiver construction is similar to the FTDX5000. The kickoff IF frequency is 9 MHz, and a low noise figure dual gate MOS FET, D-quad DBM (Double Counterbalanced Mixer) with excellent intermodulation characteristics, is implemented in the mixer section. Narrow ring SDR configuration makes it possible to utilize the narrow bandwidth crystal covering filters that have the sharp shape factor.  This achieves the amazing multi-signal receiving performance when confronted with the near challenging on-the-air interference situations.

In improver to IF down-conversion, The FTDX101 receivers implement the YAESU legendary powerful RF Front-Ends, outstanding low-noise Local Oscillators, roofing filters with precipitous shape factors, and the latest circuit configurations that we carefully selected for all circuit elements. Consequently, the proximity BDR (Blocking Dynamic Range) in the fourteen MHz band reaches 150 dB or more, the RMDR (Reciprocal Mixing Dynamic range) reaches 123 dB or more, and the 3rd IMDR (third-order Intermodulation Dynamic Range) reaches 110 dB or more.

Narrow band SDR + Direct Sampling SDR

Emphasizes Fantabulous Receiver Operation and Hybrid SDR Functionality

Digital Processing Generated Real-Time Spectrum Telescopic

The Narrow band SDR receiver removes stiff out of band signals by using a superheterodyne method, with narrow band roofing filters which significantly attenuates unwanted out of ring frequency components, and the wanted signals within the passband are converted to digital by a high resolution 18-fleck A/D converter and sent to an FPGA (Field Programmable Gate Array) for point processing.

The FT DX 101 series uses a hybrid SDR configuration that integrates a directly sampling SDR receiver in guild to view the entire band status in existent fourth dimension, with the fantabulous dynamic receiver operation achieved by the narrow ring SDR receiver excursion.

By using this hybrid SDR blueprint, the overall operation of the entire FTDX101 receiver system is improved. The Direct Sampling SDR driving the real fourth dimension Spectrum display with its large dynamic range enables the weakest signal to exist observed on the display when it appears and the Narrow Ring SDR enables that signal to be selected, filtered so decoded.

If at that place is powerful AM station near your location or in challenging operating situations where there are a lot of strong signals in the ring from Contests, DX-pedition activities, those signals exterior the pass band can be adulterate by the very effective roofing filter in the front end stage of the A/D converter. This reduces the point load on the A/D converter which is a bottleneck from the viewpoint of the entire receiving circuit. Therefore, interference is reduced making it is possible to continue to operate fifty-fifty nether such difficult conditions.

Truly Quiet and Clear Reception

Ultra Depression-Noise Local Oscillator Arrangement; 400MHz HRDDS (Loftier Resolution Directly Digital Synthesizer)

The C/N ratio (indicate-to-dissonance ratio) of the local indicate injected into the 1st mixer is an of import cistron in improving the proximity multi-indicate characteristics. The local circuit of the FTDX101 serial uses the 400 MHz HRDDS (High Resolution Straight Digital Synthesizer) method that was used in the FTDX5000. This excursion configuration is different from a generic PLL that generates a local signal. Creating the local signal by straight dividing the high frequency of 400 MHz, the theoretical PLL lockup time becomes aught, and C/North deterioration by the lockup time does not occur.

The significant improvement of the C/Due north feature by directly dividing the frequency contributes dramatically to reduce the noise in the entire receiver stage, and also ameliorate the BDR (Blocking Dynamic Range) characteristic in stiff signals proximity.

In the FTDX 101 series, in add-on to the adoption of the 400 MHz HRDDS, the latest circuit configurations that reduced noise, and carefully selected components are used. As a outcome, the phase noise feature of the local betoken achieves an excellent value of -150 dBc/Hz or less at 2kHz separation.

This low-noise, high-quality local signal contributes significantly to the multi-betoken and the ultra-close signal proximity (such as a few hundred hertz) characteristics.

Unparalleled -70 dB Maximum Attenuation VC-Melody

Newly developed VC-Tune RF Preselector with loftier precision stepping motor drive provides outstanding attenuation characteristics

Frequency automatic adjustment RF Preselector VC-Tune

In the FTDX101 series, a next-generation RF preselector VC-Melody further improves the high-performance RF μ (mu)-Tuning system adopted in FTDX9000. Using a remarkable miniaturization blueprint while producing unparalleled characteristics and maximum attenuation of -70 dB.

Newly developed VC-tune circuit drives a variable capacitor (VC) with a loftier precision stepping motor and achieved remarkable miniaturization over μ-tuning system.

VC-Tune has no annoying steps or switching relays past continuously covering the ring with a variable capacitor driven by a high-precision stepping motor following the frequency. The conventional preset method of switching coils and capacitors with relays is eliminated.

When at that place are multiple stiff signals in the band, press the "VC Melody" key and turn the MPVD (Multi-Purpose VFO Outer Dial) ring on the VFO dial to activate the high-precision stepping motor to adjust the variable capacitor. Fine tune to the optimum point that attenuates the stiff signal in the band while operating the VFO punch.

VC-Tune stores the final tuning point for each band, so when broadcast-like signals are periodically transmitted on the same frequency, that frequency tin always be attenuated past setting the VC-Tune one time.

The Highest Transmit Signal Purity

High-Quality transmission with outstanding stage noise characteristics

Transmit Final Stage produces the Highest Signal Purity

The fantabulous C/N characteristics provided past the 400MHz HRDDS (Loftier Resolution Direct Digital Synthesizer) used in the local oscillator excursion also contributes significantly to the transmitter section.  In a generic circuit, noise or distortion may occur depending on the excursion configuration and the components, upwardly to the final phase that is producing the transmit signal, even if the local point is of high quality.  In the FTDX101, a thorough examination of each element up to the final TX stage was made. The clock that divides and distributes the local signal from the 400MHz HRDDS circuit to each block, likewise as the FPGA, D/A converter, the final power amplifier etc., and carefully selecting the latest excursion configurations to improve the C/N characteristics of the entire transmitter block. The transmit signal of the FTDX101 is directly generated from a 16-bit D/A converter without passing through a mixer circuit, therefore distortion and noise are significantly suppressed.

As a outcome, loftier-quality local signal characteristics are maintained without degradation to the final stage, and the manual phase noise characteristics reach -150 dBc/Hz at 2kHz separation. FTDX101 transceiver user will appreciate the finest operation with a high-purity manual signal.

When the ring selected as MAIN Band, the LED indicates in white, and when the ring selected by SUB band, the LED indicates in bluish. At the status of manual, the LED turns ruby-red so you can instantly ostend which VFO is transmitting.

In improver, since the orange LED lights upward when you press and hold the band cardinal, y'all can utilise it to display a band that has an antenna connected or to display a band operated in DX-pedition mode every bit a memo. Below the ring key is a key for selection between manual and reception of the Primary and SUB band, and below that, there is a switching key for using the VFO knob on the MAIN or SUB tuning, and so, even when the operating split using both MAIN and SUB bands at the aforementioned time, the band control can be performed smoothly, and then tuning the wrong ring past mistake is reduced.
