Description
The MH214W is a four-channel receiver IC covering 15–25 GHz. It integrates four receive front-ends, analog baseband circuitry, ADCs, an LVDS interface, an on-chip temperature sensor, fault monitoring and SPI control. Four channels receive, digitize and transfer signals simultaneously. SPI controls operating state and channel switching; LVDS carries the ADC data.
Applications: Millimeter-wave security screening, traffic radar, industrial monitoring and fire safety.
Product status: Engineering sample.
