Abstract
A wireless transceiver device includes an operation amplification circuit, a transmitter circuit, a receiver circuit, and a transceiver control circuit. The operation amplification circuit, according to a rate parameter and a filtering parameter, filters and amplifies an input signal and outputs a processed signal. The transmitter circuit selectively uses a first ratio or second ratio as the amplification parameter, converts an input signal into an analog signal, inputs the analog signal into the operation amplification circuit, mixes the processed signal with a local oscillating frequency and then output an output signal. The receiver circuit mixes an external signal with another local oscillating frequency, inputs the mixed signal into the operation amplification circuit, and converts the processed signal into a digital signal. The transceiver control circuit selectively and electrically connects the operation amplification circuit with the transmitter circuit or the receiver circuit.
