Abstract

The invention discloses a microwave integrated module of a PIN transmit-receive switch and a limiter. The microwave integrated module comprises a transmitting branch, an antenna branch, a receiving circuit and a detection circuit. The transmitting branch is composed of a blocking condenser, a tandem switch PIN tube and a choke inductor; the receiving circuit is composed of a 1 / 4 wavelength transmission line, an earth parallel switch PIN tube, a small power amplitude limiting PIN tube, an earth parallel choke inductor and an amplitude limiting control choke inductor; the transmitting branch is composed of a blocking condenser and a coupler; and the detection circuit is composed of a detector diode, a capacitor and a resistor. The earth parallel switch PIN tube on the receiving branch is shared by a transmit-receive switch function and an amplitude limiting function, thereby reducing the number of cascaded PIN tubes of the receiving branch and reducing the insertion loss of the reducing branch on the premise of guaranteeing the power capacity of the switch and the limiter.

Description

technical field [0001] The invention belongs to the technical field of radio frequency front ends of electronic equipment, in particular to a microwave integrated module of a PIN transceiver switch and a limiter, which is used for transceiving conversion of radio frequency front ends of electronic equipment. Background technique [0002] The PIN transceiver switch is used for the transmission and reception conversion of the front-end of radar, communication and other electronic equipment. The antenna of the equipment is connected to the transmitter or receiver through the transceiver switch to transmit or receive electromagnetic wave signals, so as to detect targets and transmit information. The limiter is installed between the transceiver switch and the receiver to protect the receiver from high-power signal limiting and prevent external high-power signals from damaging the receiver. When the system is in the receiving state, the microwave signal received by the antenna pas...
