BROADBAND AMPLIFIER SYSTEM USING A 3dB QUADRATURE COMBINER TO DYNAMICALLY MODULATE LOAD IMPEDANCE |
摘要 |
Systems and methods are provided for modulating a radio frequency (RF) carrier signal with a baseband input signal and amplifying the modulated RF carrier signal to provide an amplified RF signal. A quadrature combiner is configured to provide the amplified RF signal at an associated output port. A main amplifier is configured to receive a first modulated RF signal and provide a main output to one of a through port and a coupled port of the quadrature combiner. An auxiliary amplifier is configured to receive a second modulated RF signal and provide an auxiliary output to an isolation port of the quadrature combiner. |
