Diy Kit 9 band BPF interface module
This BPF board is specially designed for easy and fast connection transceiver board to antenna and PA module HF radio.
This will work great with SDR transceivers and receivers such as RTL SDR, HERMES, ODYSSEY, HiQSDR, Red Pitaya and many others.
This module has 9 bands BPF, ATT 20dB, PREAM RX 10dB. All bands, att and preamp switching is done using mechanical relays, which allows you to realize the high dynamic range of your transceiver board. Also, there ist has PREAM TX module on the board. You can easily connect your PA module, all switching is done on this board.
The kit includes everything you need to assemble this 9 band interface board – printed circuit board, complete set of parts (band coils already wound), assembly and configuration instructions in English, circuit diagram.
