Microwave amplifier and other microwave components

摘要

A broad band, balanced microwave component, such as an amplifier, includes an input Lange coupler having a first center frequency and an output Lange coupler having a second center frequency. The center frequencies of the two Lange couplers are offset or the coupling is different so that at least one of the cross-over points of the input Lange coupler is offset in frequency from both the cross-over points of the output Lange coupler. The pair of Lange couplers so offset in frequency yields no more than one peak in gain which is readily equalized by single-ended amplifiers within the balanced amplifier.
