Abstract

The invention discloses an RFID (Radio Frequency Identification) large power control device. The RFID large power control device comprises a communication link I, a communication link II and a control conversion unit, wherein the communication link I mainly consists of a first blocking unit, a first switch unit, a second blocking unit and a second switch unit; and the communication link II mainly consists of a first blocking unit, a first switch unit, a third switch unit and an impedance matching unit. The RFID large power control device is suitable for a large power (over 200W) signal control radio frequency switch. On the basis of ensuring relatively low loss (0.1dB), the power handling capacity of a switch is increased, and the production cost is lowered. Meanwhile, the RFID large power control device is reasonable in structure and PCB (Printed Circuit Board) layout, and runs stably.

Description

technical field [0001] The invention belongs to the field of power switches, and in particular relates to an RFID high-power control device. Background technique [0002] At present, the radio frequency switches used in the time-division duplex transceiver switches used in communication systems are generally divided into two types: a miniaturized switch for MEM microassembly and a PIN radio frequency switch for the transmission channel. The disadvantages of the former are low power, short life and high cost; the disadvantages of the latter are large insertion loss, large volume and high power consumption. Contents of the invention [0003] In view of this, the present invention aims to propose an RFID high-power control device capable of controlling high-power signals of radio frequency channels. [0004] In order to achieve the above object, the technical solution created by the present invention is achieved in this way: [0005] An RFID high-power control device is cha...
