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.
Claims9
An integrated active satellite antenna module, comprising:
- a first input end for importing a passive antenna signal thereof;
- a second input end for importing an active antenna signal thereof;
- a low loss filter for filtering noise and a band signal of the passive antenna signal;
- a low noise amplifier for amplifying the band signal;
- a switch for receiving the band signal amplified via the low noise amplifier and receiving the active antenna signal imported via the second input end for switching the antenna signal;
- a chip for demodulating the antenna signal received from the switch, and
- a output end for exporting the antenna signal demodulated;
- wherein:
- the first input end, the second input end, the low loss filter, the low noise amplifier, the switch, the chip, and the output end are electrically connected in order;
- and
- the electric signal has two directions:
- I. The passive antenna signal imports from the first input end, and processes the low loss filter, the low noise amplifier, the switch, the chip, and the output end in order;
- and
- II. The active antenna signal imports from the second input end, and processes the switch, the chip, and the output end in order.
