The invention provides a microstrip thin-film resistor and a waveguide power synthesis network thereof, which can solve the problems of power synthesis and miniaturization of a power amplifier. The microstrip thin-film resistor comprises a ceramic substrate, a TaN resistor and a microstrip probe, the TaN resistor and the microstrip probe are arranged on the ceramic substrate, the TaN resistor clings to the edge of the ceramic substrate, the TaN resistor is connected with the microstrip probe, and the microstrip probe extends to the opposite edge of the ceramic substrate. The waveguide power synthesis network comprises a power distribution network, a power amplifier module and a power synthesis network, the power distribution network divides microwave signals into N paths of signals with the same amplitude and the same phase, each path of signals is amplified by the power amplifier module and then fed into the power synthesis network, and the microstrip thin-film resistor is arranged atthe joint of the power distribution network and the power synthesis network.

Description

technical field [0001] The invention relates to the field of multi-channel waveguide synthesis, in particular to a microstrip thin film resistor and a waveguide power synthesis network thereof. Background technique [0002] With the development of microwave and millimeter-wave solid-state devices, solid-state microwave and millimeter-wave high-power amplification technology has attracted widespread attention. Due to the limited output power capability of a single MMIC, it is difficult to meet the requirements of engineering applications. Power combining technology is the most important and effective way to obtain high-power solid-state microwave and millimeter wave sources. The performance of power distribution / synthesis technology directly affects the energy distribution and synthesis efficiency of the entire system. The most commonly used synthesis methods in the industry include microstrip synthesis, radial synthesis, and waveguide synthesis. [0003] Microstrip synthes...

AI Technical Summary

Problems solved by technology

[0003] The microstrip synthesis network is small in size, but at mmWave frequency bands, the insertion loss becomes very large and the power capacity is limited

Radial combination has inherent advantages in multi-channel power combination, with small insertion loss and large power capacity, but the volume is very large, and its application in miniaturized devices is limited.
