Overview
The ADF5904WCCPZ is a 4-channel, 24 GHz receiver downconverter produced by Analog Devices Inc. This component is designed for high-frequency applications, particularly in the realm of radar systems. Each channel of the ADF5904 includes a single-ended RF input with an on-chip balun, followed by a differential low noise amplifier (LNA) and a downconverter mixer with differential output buffers. The device also features a shared LO path with an on-chip balun, converting the single-ended input to a differential signal to drive the mixer.
The ADF5904 is available in a compact 32-lead Lead Frame Chip Scale Package (LFCSP) and is qualified for automotive applications, ensuring it meets the stringent quality and reliability requirements of the automotive industry.
