1-18GHz IP68 Waterproof Microwave Down Converter Component
ZDTECH 1-18GHz wideband down-converter covers 1~18GHz RF band with two switchable IF output modes. It integrates 6-bit digital RF & IF attenuators, delivers stable 50dB±1dB gain and over 60dBc SFDR with excellent phase noise and image rejection. It supports internal/external reference clock switching, remote control via Ethernet or RS422, and real-time monitoring of voltage, temperature and lock status. Compact 100×100×20mm unit with IP68 waterproof grade resists wide temperature and vibration, ideal for microwave and RF test systems.
