Abstract :
The use of asymmetrical bandpass LC filters as input matching networks for low noise amplifiers is investigated. The use of these filters instead of symmetrical bandpass filters for wideband impedance matching allows simpler structures for the matching of unequal resistances, some voltage gain, and stronger attenuation at high-frequency.
