Method and apparatus for processing signals at time division duplex transceiver

摘要

Provided is a time division duplex (TDD) transceiver. A receiver chain processing received signals and a transmitter chain processing signals to be transmitted share an electronic component used in a circuit, such as an amplifier, a mixer, a filter, etc., so that the size of a semiconductor die needed to manufacture a radio frequency (RF) chip can be reduced.

主权项

1. A method for processing signals using a time division duplex (TDD) transceiver device, the method comprising:
using a transmitter chain to process signals to be transmitted; and using a receiver chain to process received signals, wherein the transmitter chain and the receiver chain share at least one electronic component and the at least one electronic component performs a first function in the transmitter chain and performs a second function different from the first function in the receiver chain, wherein the transceiver device includes a digital baseband chip and a radio frequency (RF) chip, the method further comprising: converting first parallel digital signals for controlling a gain of a variable gain amplifier of the RF chip into serial digital signals using the digital baseband chip; and transmitting the serial digital signals from the digital baseband chip to the RF chip.
