The DTRX2 card is a dual channel transmit/receive mmWave radio platform, built around off-the-shelf components, to achieve high bandwidth and high performance. It directly interfaces with the Xilinx Zynq UltraScale+ RFSoC ZCU208 Evaluation platform, hosting the Xilinx Zynq® UltraScale+™ multi-channel RFSoC Gen3. Specifically, the kit provides 2 TX and RX up/down converters to perform the IF to RF modulation and demodulation. This transceiver design takes advantage of the multi-gigasample RF-sampling converters within the Xilinx RFSoC Gen-3 device.The mmWave range of the radio card is 19 to 31GHz, with an adjustable IF center frequency around 4GHz. Both transmitters and receivers have their dedicated ½ LO PLL circuit, driving harmonic mixers
