摘要: The present invention discloses a gain amplifier, capable of concurrently operating at three different frequency bands. amplifier comprises an amplification stage for amplifying signal applied to input the and triple-band resonance load connected between DC bias voltage stage. uses set reactive elements provide match in first band, second band third such as 2.4 GHz, 5.8 GHz 9.0 GHz. According invention, it can effectively in-band interference suppression various multi-standard coexist communication systems.
