V-band miniaturized low-power-consumption high-power digital phase shift network

Abstract

The invention provides a V-band miniaturized low-power-consumption high-power digital phase shift network. The network comprises an equipment shell, and the equipment shell is internally provided witha high-power power division network module for carrying out power distribution on a 108MHz-174MHz radio frequency signal, eight phase shift network modules for carrying out seven-bit digital phase shift on the 108MHz-174MHz radio frequency signal, and a control circuit for carrying out phase shift state control on the device; and the high-power power division network module is integrally connected with the equipment shell, the eight phase shift network modules are in one-to-one correspondence with eight output ports of the high-power power division network module and are connected in series through SMP blind-mating radio frequency connectors, the eight phase shift network modules are respectively provided with a control pin, and the control circuit is connected with the control pins of the phase shift network modules. The network is reasonable in structure, overcomes the defects that a conventional digital phase shifter is large in size, small in passing power, large in power consumption of a power supply, large in bias voltage and low in response speed, and has a certain phase shift tuning function.

Description

technical field [0001] The invention relates to the field of radio frequency and microwave technology, specifically a V-band miniaturized, low-power, and high-power digital phase-shifting network. Background technique [0002] In recent decades, phased array radar has been widely used. As one of the core components of the array system, the digital phase shifter has been developed rapidly due to its unique electronic scanning method, which has the advantages of flexible scanning, fast beam change and multi-function. The quality of the phase shift accuracy and response speed of the phase shifter directly affects the accuracy and scanning speed of the antenna beam, and plays a key role in the performance of the radar. [0003] With the development of radio frequency technology and semiconductor materials and processes, digital phase shifter chips based on MMIC technology have become the mainstream of modern phase shifters. In the L-band and above frequency bands, MMIC digital...
