Description
AI
The ADF5901 is a 24 GHz Tx monolithic microwave integrated circuit (MMIC) with an on-chip, 24 GHz VCO with PGA and dual Tx channels for radar systems. The on-chip, 24 GHz VCO generates the 24 GHz signal for the two Tx channels and the LO output. Each Tx channel contains a power control circuit. There is also an on-chip temperature sensor.Control of all the on-chip registers is through a simple 4-wire interface.The ADF5901 comes in a compact 32-lead, 5 mm × 5 mm LFCSP package.ApplicationsAutomotive radarsIndustrial radarsMicrowave radar sensorsIndustrial sensorsPrecision instrumentationTank level sensorsSmart sensorsDoor openingEnergy savingCommercial sensors: object detection and trackingCars, boats, aircraft, and UAVs (drones): collision avoidanceIntelligent transportation systems: intelligent traffic monitoring and controlSurveillance and security
