Abstract
This paper presents a switchable dual-input low-noise amplifier (LNA) with notch filters for the switchable dual-circular polarization satellite receiver. Notch filters with different resonant frequencies provide a wideband stopband suppression and avoid degradation results from the process variation. The measured small-signal gain is 19.2 dB, and the simulated noise Figure (NF) is 1.55 dB at 19 GHz. The measured insertion loss is better than 15 dB from 24.1 to 30.5 GHz, effectively suppressing the leakage signal from the transmitter. ? 2021 IEEE.
