Patent ID: 6954104

Claim:
A system for monitoring a deliverable RF power of an amplifier operable on a monolithic microwave integrated circuit (MMIC), the system comprising: circuitry configured to capture, on the MMIC, a first portion of an RF signal transmitted from the amplifier to a load, and a second portion of the RF signal reflected from the load back to the amplifier; circuitry configured to generate, on the MMIC, a first signal proportional to an RF power of the first portion of the RF signal, and a second signal proportional to an RF power of the second portion of the RF signal; circuitry configured to subtract a first reference signal from the first signal to produce a third signal, and a second reference signal from the second signal to produce a fourth signal; and circuitry configured to subtract the fourth signal from the third signal to produce an output signal proportional to the deliverable RF power of the amplifier to the load.
