The ADF5904 from Analog Devices is a 4-channel, 24 GHz receiver downconvertor. Each channel contains 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 RF LO path also has an on-chip balun. It is available in a compact 32-lead, 5 mm × 5 mm LFCSP package. The downconverter can be used in automotive radars, industrial radars and microwave (μW) radar sensors applications.
