Problems solved by technology

[0005] Since the distance between the two antennas is very close, and the TX power is usually much larger than the RX power, this interference will seriously reduce the receiving sensitivity of the RX signal

Embodiment Construction

[0022] The following descriptions are preferred embodiments for implementing the present invention. The following examples are only used to illustrate the technical characteristics of the present invention, and are not intended to limit the scope of the present invention. The protection scope of the present invention shall prevail as defined by the appended application claims.

[0023] As mentioned above, mobile electronic devices (eg, communication devices) can now support multiple radio access technologies (RAT) communication. Therefore, a mobile electronic device can provide more than one wireless communication service. At present, high-performance multi-standby (multi-standby) and even multi-talk (multi-talk) communication devices have been developed. Therefore, different RAT modules in one communication device can simultaneously send and / or receive radio frequency (radio frequency, RF) signals. When a RAT module sends a TX signal, and the frequency band of the RAT modu...

Abstract

A communications apparatus includes a baseband module, a radio transceiver module, a front- end signal processing module and an antenna switch module. The front-end signal processing module is coupled to the radio transceiver module and pre-processes RF signals received from at least one antenna to generate pre-processed RF signals. The front-end signal processing module includes at least a first bandpass filter and a second bandpass filter. A frequency range of a first passband of the first bandpass filter overlaps with a frequency range of a second passband of the second bandpass filter, and the frequency range of the second passband is wider than the frequency range of the first passband.

Description

[0001] Cross References to Related Applications [0002] The scope of claims in this application claims priority to US Provisional Application No. 61 / 581,336, filed December 29, 2011. This application is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a communication device that avoids signal interference, and more particularly, relates to a communication device that avoids signal interference and a method for avoiding signal interference in the communication device.
