ABSTRACT:
An integrated active satellite antenna module has a low loss filter, a low noise amplifier, a switch, a chip, two input ends and an output end. A front-end microwave circuit is used for resolving the mutual coupling effect between the satellite antenna and the other antennas operating at any other frequencies in an integrated active satellite antenna module, and furthermore it provides the simultaneous operating condition for the individual antenna by improving the isolation level between the satellite frequency band and the other frequency band.
