Wireless communication device for concurrently receiving multiple types of signals and associated method

A method for concurrently receiving multiple types of signals in a wireless communication device, comprising:

• utilizing at least one pre-stage low noise amplifier (LNA) of the wireless communication device to amplify an initial signal received by an antenna to generate at least one input signal, wherein the initial signal comprises the multiple types of signals, and the multiple types of signals comprise a first-type signal and a second-type signal;
• utilizing a first conversion circuit of the wireless communication device to perform a conversion operation upon the at least one input signal to generate a first converted signal;
• utilizing a second conversion circuit of the wireless communication device to perform the conversion operation upon the at least one input signal to generate a second converted signal;
• utilizing a first filter of the wireless communication device to filter the first converted signal to reduce powers of signals other than the first-type signal among the first converted signal, in order to make a first receiving path coupled to the first filter process the first-type signal within the first converted signal;
• and
• utilizing a second filter of the wireless communication device to filter the second converted signal to reduce powers of signals other than the second-type signal among the second converted signal, in order to make a second receiving path coupled to the second filter process the second-type signal within the second converted signal.
