Embodiment Construction
[0019] The function of the circulator 6 in the traditional millimeter-wave band injection-locked power amplifier is to ensure the one-way transmission of the millimeter-wave signal and provide a channel for the output signal at the same time. Such as Figure 4 As shown, the 3dB waveguide slot bridge power distribution network consists of two rectangular waveguides with the same size and a common narrow wall, and its coupling mechanism is a continuous coupling slot on the common wall. Due to the effect of the coupling slit, the phase relationship of the coupled port is 90° behind that of the through port and the amplitude relationship of the equalized output is formed. Therefore, it is determined that it can be used to realize the signal one-way transmission function of the circulator, and also ensure the uniqueness of the output signal channel after synthesis.

The invention relates to a millimeter waveband signal power amplification and synthesis method. In a power distribution and power synthesis multiplex network formed by utilizing a special phase relation that a coupling port of a millimeter wave 3dB waveguide slot bridge is 90 degrees backward than a straight-through port, two millimeter wave oscillators form two injection locking power amplifyingcircuits; a path of millimeter waveband small-power signals are injected to the waveguide slot bridge, and are subjected to power distribution to form two paths of millimeter waveband small-power signals with equal amplitude and 90-degree phase difference for output; the two injection locking power amplifying circuits respectively perform lock-in amplification on the two paths of millimeter waveband small-power signals; and the power signals subjected to lock-in amplification are subjected to power synthesis through the waveguide slot bridge to form millimeter wave high-power signals with thesame phase as the power signals subjected to injection lock-in amplification. Two circulators and a millimeter wave power distribution / power synthesis network are reduced, so the equipment amount, volume and weight of a millimeter waveband injection lock-in amplifier power synthesis system are greatly reduced.
