Technical field [0001] The invention provides a fixed-supported beam T-junction direct heating microwave signal detection instrument, which belongs to the technical field of microelectronic mechanical systems. Background technique [0002] In the context of modern technology, microwave signal detection is used in phase modulators, phase shift keying (PSK), phase locked loops (PLL), microwave positioning, antenna phase pattern testing, near field diagnosis, and measurement of various microwave devices. Phase characteristics and so on have extremely wide applications. These systems urgently need electronic devices with light weight, small size, low power consumption and high integration in practical applications. However, the existing microwave power, phase, and frequency detectors are discrete circuits and large in size. Therefore, there is an urgent need for a system that can achieve integrated detection of three microwave parameters to meet the application requirements of the m...
