Trx-Duo SDR Transceiver | Dual 16bit ADC with ZYNQ7010 | 2TX & 2RX DDC DUC SDR | Red Pitaya POWER-SDR SDR# SDR-Console

TRX-duo is an SDR device that supports dual-channel physical reception and transmission. It utilizes 2 x 16Bit ADC LTC2208 for the direct sampling of the 10KHz-60MHz RF signal. It features with high dynamic range, high sensitivity, and high feasibility of remote deployment(operation). A 14bit DAC is used for the dual transmission. Because the firmware is based on the well-known Red Pitaya, there are various apps that could work with it, the HDSDR, SDR#,  PowerSDR,  SDRConsole (V3) etc…

Note:

1. The RF output from TRX DUO is only 25mW, so a RF power amplifier and LPF filter is needed for generating RF powers more than that if you let it work as a ham radio transceiver.
2. Due to the Global Chip Shortage, the price of ADCs and FPGAs soars, and we can’t source them with a fair and reasonable price. As a result, some USED ADCs and FPGAs are used in this product. The USED FPGAs are from some controller boards of bitcoin mining machine, these FPGAs were not used for computing and they don’t age like the GPUs on the Graphic Cards. If you mind this, please don’t place an order.
