24 GHz VCO and PGA with 2-Channel PA Output

The ADF5901 is a 24 GHz Tx monolithic microwave integrated circuit (MMIC) with an on-chip, 24 GHz VCO with PGA and dual Tx channels for radar systems. The on-chip, 24 GHz VCO generates the 24 GHz signal for the two Tx channels and the LO output. Each Tx channel contains a power control circuit. There is also an on-chip temperature sensor.

Control of all the on-chip registers is through a simple 4-wire interface.

The ADF5901 comes in a compact 32-lead, 5 mm × 5 mm LFCSP package.
