Dual-mode wireless transceiver device

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.

AI Technical Summary

Benefits of technology

The patent describes a dual-mode wireless transceiver device that can receive and transmit signals of two different wireless communication standards. The device includes a digital-to-analog conversion circuit, a second mixer circuit, a filter amplifier circuit, a first mixer circuit, an analog-to-digital conversion circuit, and a transceiver control circuit. The device can selectively connect to either a first or a second antenna for transmitting signals. The filter amplifier circuit filters and amplifies signals based on a filtering parameter and a rate parameter. The operation amplification circuit selectively amplifies the signals using the corresponding rate parameter. The transmitter circuit performs digital-to-analog conversion, filtering, and amplification, while the receiver circuit performs analog-to-digital conversion and filtering. The transceiver control circuit controls the operation amplification circuit and the transmitter circuit for selecting the appropriate mode. The technical effect of this patent is to provide a versatile wireless transceiver device that can communicate with different standards while filtering and amplifying signals effectively.

Problems solved by technology

This is contradictory with a tendency that the chip needs to be manufactured increasingly small.

Additionally, because Wi-Fi and Bluetooth each are an independent circuit, the chip needs much and complex control.
