Abstract
A phased-array receiver that may be effectively implemented on a silicon substrate. A receiver includes multiple radio frequency (RF) front-ends, each configured to receive a signal with a given delay relative to the others such that the gain of the received signal is highest in a given direction. The receiver also includes a power combination network configured to accept an RF signal from each of the RF front-ends and to pass a combined RF signal to a down-conversion element, where the power distribution network includes a combination of active and passive components. Each RF front-end includes a phase shifter configured to delay the signal in accordance with the given direction and a variable amplifier configured to adjust the gain of the signal.
