ANALOG SIGNAL PROCESSING DEVICE FOR PHASED ARRAY ANTENNAS

摘要

A signal processing device includes a device package, processing circuitry and biasing circuitry. The processing circuitry is packaged in the device package and is operative to receive one or more Radio Frequency (RF) input signals from one or more antenna elements via one or more pre-amplifiers that are separate from the device, and to process the RF input signals so as to produce an RF output signal. The biasing circuitry is packaged in the device package and is operative to produce one or more biasing signals for biasing the pre-amplifiers.
