Abstract

The invention relates to a transceiver isolation circuit, a TDD wireless transceiver circuit and a base station. Wherein the transceiver isolation circuit includes a first microstrip line, which is used to transmit the signal to be transmitted output by the signal transmitting unit; a second microstrip line, which is connected in series with the first microstrip line, and is used to transmit the signal to be transmitted to the common signal of the antenna unit. end; the first PIN high-speed switch, the first end is connected between the first microstrip line and the second microstrip line, the second end is grounded, and the enable control end is used to connect the enable output end of the digital processing unit for Control the grounding state of the second microstrip line according to the enable level; the enable level is the level signal output by the digital processing unit according to the TDD switching time slot; the second PIN high-speed switch, the first end is used to connect the common of the antenna unit terminal, the second terminal is used to connect the input terminal of the signal receiving unit, and the enable control terminal is used to connect the enable output terminal of the digital processing unit, and is used to control the on-off state of the input terminal of the signal receiving unit according to the enable level. Improved signaling performance.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a transceiver isolation circuit, a TDD wireless transceiver circuit and a base station. Background technique [0002] With the development of communication technology, the fourth-generation mobile communication technology has been widely used, and the fifth-generation mobile communication technology has also been released and gradually promoted. Different communication systems adopt different signal modulation methods, which can be divided into TDD (Time Division Duplexing, time division duplex) mode and FDD (Frequency Division Duplexing, frequency division duplex) mode from the duplex communication mode adopted. In TDD mode, the power amplifier used by the base station not only needs to output high power, but also needs to avoid damaging the function of the low-noise receiving circuit. [0003] For the wireless receiving and transmitting circuit in TDD mode, the tradition...
