Overview
The ADF5904ACPZ-RL7 is a 4-channel, 24 GHz receiver downconverter produced by Analog Devices Inc. This component is designed for high-frequency applications, particularly in the realms of automotive and industrial radars, as well as microwave radar sensors. 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 an on-chip balun in the LO path and is controlled via a simple 3-wire interface. It is packaged in a compact 32-lead Lead Frame Chip Scale Package (LFCSP) with dimensions of 5 mm x 5 mm.
