6-18GHz 4 channel RX Down Converter Module
ZD-DCM-6/18G
This 6-18GHz 4-channel RX down converter module integrates four independent receiving channels, covering 6-18GHz RF input and outputting fixed 1875MHz IF with optional 50MHz/100MHz IF bandwidth. It features noise figure below 10dB, 65dB image rejection and 85dB IF rejection with outstanding linearity. Equipped with 0-31dB adjustable RF/IF attenuators and a 1W input limiter, it can withstand +15dBm RF input without damage. The module supports dual control interfaces including RS422 and Ethernet, and comes with built-in BITE self-test function. LED indicators display power, connection and fault status in real time. With compact dimensions under 25×20×4cm, it is widely used for microwave signal acquisition and RF test system integration.
Quantity:
This 6-18GHz 4 channelrx down convert module is a high-performance multi-channel RF receiving frequency conversion device with four independent parallel receiving channels. Its RF input covers full 6-18GHz range and outputs fixed 1875MHz IF, with optional 50MHz and 100MHz IF bandwidth. This professional rx down convert unit features noise figure less than 10dB, 65dB image rejection and 85dB IF rejection, with +10dBm IP3 for excellent linear performance. It is equipped with 0~31dB digital RF/IF attenuators and a built-in 1W input limiter to protect the module from +15dBm input power. The compact 4 channel 6-18GHz rx down convert device supports RS422 and Ethernet dual control ports, integrated BITE self-test function and LED monitoring indicators. With dimension less than 25×20×4cm and dual OCXO reference outputs, it serves as essential hardware for multi-channel microwave signal capture and RF test system integration.
