Method and system for utilizing diplexer/duplexer for WCDMA operation as a filter for supporting GSM-based operation
First Claim
1. A method for handling wireless signals, the method comprising:
- receiving first wireless protocol signals and second wireless protocol signals via one or more duplexers coupled to a receiver in a wireless device; and
selecting, via a plurality of switching elements, within said receiver one of a processing path for said received first wireless protocol signals and a processing path for said received second wireless protocol signals, wherein;
said plurality of switching elements directly couple each of said one or more duplexers to an input of a low noise amplifier of said processing path for said received first wireless protocol signals, and to an input of another low noise amplifier of said processing path for said received second wireless protocol signals; and
each of said one or more duplexers band pass filters said received second protocol signals.

Abstract
Aspects of a method and system for utilizing a diplexer/duplexer for WCDMA operation as a filter for supporting GSM-based operation are provided. A receiver portion of a wireless device may receive WCDMA signals and GSM signals via at least one duplexer or diplexer. The duplexers may enable bandpass filtering of received GSM signals. The wireless device may enable receiving the WCDMA signals and the GSM signals via a single antenna coupled to the duplexers. The receiver portion may also enable selecting a processing path for received WCDMA signals or a processing path for received GSM signals. The receiver portion may enable amplification and filtering of the WCDMA signals. Filtering of the WCDMA signals may be performed via surface acoustic wave (SAW) filters. The receiver portion may also enable filtering of the GSM signals via the duplexers and amplification of the filtered GSM signals.
