Abstract
A composite high frequency component and a mobile communication apparatus incorporating the same which needs no matching circuits and can easily be miniaturized. The composite high frequency component is constituted of a diplexer, high frequency switches, high frequency filters, and surface acoustic wave filters. The diplexer is formed by first inductors and first capacitors. The high frequency switches are formed by diodes, second inductors, and second capacitors. The high frequency filters are formed by third inductors and third capacitors.
Claims7
A composite high frequency component included in a microwave circuit having a plurality of signal paths corresponding to respective frequencies, the composite high frequency component comprising:
- a diplexer which accepts transmitted signals from the plurality of signal paths at a time of transmission, and delivers received signals to the plurality of signal paths at a time of reception;
- a plurality of high frequency switches dividing the plurality of signal paths, respectively into transmission sections and reception sections;
- a plurality of high frequency filters connected in respective ones of the signal paths;
- a plurality of surface acoustic wave filters connected respectively to the reception sections at the rear of the plurality of high frequency switches;
- and
- a multi-layer substrate comprising a plurality of laminated ceramic sheet layers in which the diplexer, the high frequency switches, the high frequency filters, and the surface acoustic wave filters are integrated.
