Switched rf amplifiers

SpletTuned IF Amplifier Applications. by John Chung Introduction. The LTC6431-20 and LTC6433-15 are single-ended RF/IF gain block amplifiers that feature very high OIP3 with low noise and a gain of 20dB and 15dB respectively. The unique combination of high linearity, low noise and low power dissipation make this an ideal candidate for many … Splet27. jan. 2024 · This paper presents a nonlinear analytical model for an inverter-based switched-capacitor Class-D RF power amplifier (SCDPA). The root causes of the SCDPA AMAM and AMPM nonlinearities are studied. The major factors affecting SCDPA nonlinearities are identified as the unequal on-resistances of selected cell and unselected …
