PROBLEM TO BE SOLVED: To provide a high frequency amplifier that is adequate for high frequency signal processing and has sufficiently high gains at high frequencies.SOLUTION: An exemplary multipath feedforward amplifier 100 includes a plurality of amplification stages 20, 22, 24, 28, 120, and 122 configured to form at least partially distinct amplification paths 12, 14, 16, and 18 extending from an input terminal IN to an output terminal OUT, each amplification path defined by a corresponding subset of the plurality of amplification stages 20, 22, 24, 28, 120, and 122, where at least one amplification stage 120, 122 is a band pass resonator. The multipath feedforward amplifier 100 maximizes a gain at a frequency of interest by having an amplification path 18 that cascades band pass resonators 120, 122.SELECTED DRAWING: Figure 3 |
