Qualified for automotive applications
The ADF5904 is a 4-channel, 24 GHz, receiver downconverter.
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.
Control of the on-chip registers is through a simple 3-wire
interface.
The ADF5904 comes in a compact 32-lead, 5 mm × 5 mm
LFCSP package.
