A microwave tr component with ultra-wide working bandwidth

Abstract

The invention discloses a microwave TR assembly with an ultra-wide working bandwidth, which consists of a bidirectional amplifier, a one-to-four power divider, and eight TR channels connected to antennas to form a transmission link and a reception link; each TR channel includes a power amplifier , isolator, transceiver switch chip, limiter, first-stage low-noise amplifier, and multifunctional chip integrated on LTCC multilayer circuit substrate, transmit signal adjustable phase shifter, transmit signal drive amplifier, adjustable attenuator, Received signal adjustable phase shifter, two-stage low-noise amplifier; by integrating multi-functional chips on the LTCC multilayer circuit substrate, the number of microwave chips and their interconnection circuits is reduced as much as possible, and the microwave grounding of the LTCC multilayer circuit substrate is used continuously Better performance, which makes the working bandwidth wider, combined with the adjustable phase shifter and adjustable attenuator set in each transmitting and receiving channel to adjust the phase and amplitude of the signal fixedly, ensuring the amplitude and phase of the sending and receiving signals of each TR channel consistency.

Description

technical field [0001] The invention relates to the field of active phased array radar, in particular to a microwave TR assembly with ultra-wide working bandwidth. Background technique [0002] Radar equipment is mainly used for target detection and trajectory tracking; communication equipment is mainly used for information and intelligence transmission; electronic countermeasure equipment is used for monitoring, intercepting information, identifying danger and warning, and guiding interference; with the development of each system, the performance All have been improved, and the cost, weight, and platform space occupation of each system have increased. [0003] The integrated integrated radio frequency system of radar and electronic warfare uses phased array radar as the carrier, adopts a common active phased array antenna, and uses multiple beams to realize multi-functions such as radar, communication, and electronic warfare, which can not only reduce the cost of electronic...

AI Technical Summary

Problems solved by technology

[0006] The working bandwidth of traditional components is generally 10%, for example, the center frequency is 6GHz, and the working bandwidth is 5.7-6.3GHz. To achieve ultra-wide working bandwidth, it is necessary to add a frequency synthesis module, which makes the structure of TR components more complex and cannot be realized. Light and small; and the wider the bandwidth, the more difficult it is to adjust the phase and amplitude consistency

[0007] Therefore, the existing technology still needs to be improved and developed
