AI Technical Summary

Technical Problem

Existing multi-channel transceiver systems have low integration, high cost, limited frequency bands and channels, low yield and high manufacturing cost due to thin-film multilayer circuit technology, and poor noise figure and linearity due to silicon-based processes.

Method used

The first single-pole four-throw switch, the first transmitting channel, the second transmitting channel, the first receiving channel, the second receiving channel, and the second single-pole four-throw switch are integrated on the same chip, and the conduction and shutdown of each channel are controlled by the control unit. Multi-band and multi-channel signal processing is achieved by using logic control signals.

Benefits of technology

It improves chip integration, reduces costs, increases output power, improves linearity and noise, enables multi-band and multi-channel applications, and expands the application range of the chip.

Abstract

This invention relates to the field of wireless communication technology and provides a multi-channel transceiver chip. The multi-channel transceiver chip includes a chip, a first single-pole four-throw switch, a first transmit channel, a second transmit channel, a first receive channel, a second receive channel, and a second single-pole four-throw switch, all integrated within the chip. The input terminal of the first single-pole four-throw switch is connected to the transceiver port, the first output terminal of the first single-pole four-throw switch is connected to the input terminal of the first transmit channel, and the second output terminal of the first single-pole four-throw switch is connected to the input terminal of the second transmit channel. First to fourth logic control signals of the control unit control the first and second transmit channels to conduct, respectively, and fifth to eighth logic control signals control the first and second receive channels to conduct, respectively. This invention enables multi-band, multi-channel applications.
