Method and apparatus for optimum biasing of cascaded MOSFET radio-frequency devices |
摘要 |
Generally, the invention relates to a method and apparatus to improve the performance of multi-stage radio frequency linear power amplifiers. More particularly, the present invention discloses a cascaded gain expansion stage and gain compression stage at differing bias levels to produce an amplifier with superior linearity and lower intermodulation distortion and adjacent channel power than any single stage by alone.
