HF/50 MHz 100 W All Mode TransceiverFT-450 Automatic Antenna Tuner ATU-450 optionalFT-450AT With Built-in ATU-450 Automatic Antenna TunerThe Real DX Receiver!The 67.899 MHz 4 pole roofing filter (MCF)and 8 band-pass filters at the RF stateprovide excellent suppressions of out-ofbandinterference.The interference-filtering begins in the "RF" stages, with adouble conversion superhetrodyne (1st IF 67.899 MHz / 2nd IF24 kHz) system. And the 8 band-pass filters at the RF inputthat help eliminate out-of-band interference, followed by the RFAMP (2SK520 x 2) to led into the active DBM (1st local) willpromise its excellent dynamic range. At its 1st IF stage, a powerfuland excellent shape factor 4 pole roofing filter with a bandwidthof 10 kHz substantially reduces adjacent signal interference.Then, YAESU’s high performance DSP at the 2nd IF stage / 24kHz permits easy management of AGC, interference rejection,audio tone control, and noisereduction, for clear and quietreception. The 20 dB ATT(Attenuator) and IPO (InterceptPoint Optimization) featureallow the operator to optimizethe characteristics of thereceiver front end to improveits dynamic range.BPFMCF20dBATTBPFReceiver Block DiagramIPO "ON"RFAMP2SK520x2J-FETActiveDBM1stLocalWorld-Class Performance in an easy-tooperateHF/50 MHz transceiver packagewith Yaesu's unique IF DSP.The legendary YAESU IF DSP system, well reputedamong top and world class DX operators, is nowavailable in an easy to operate package. The newIF DSP system uses an ADSP-BF531SBST IC,ANALOG DEVICE, with high speed 16-bit floatingpoint architecture.Designed and programmed with unique objective of"Enhanced Transmit Signal Quality" and "AdvancedReceiving Interference Suppression".
