Overview
The ADF5904WCCPZ-RL7 is a 4-channel, 24 GHz receiver downconverter produced by Analog Devices Inc. This component is designed for high-performance applications in radar systems, including automotive and industrial radars, as well as microwave radar sensors. It features a compact 32-lead Lead Frame Chip Scale Package (LFCSP) with dimensions of 5 mm × 5 mm, making it ideal for space-constrained designs. 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 includes an on-chip temperature sensor and supports a wide operating temperature range from -40°C to +105°C.
