Big device connection, and connect by cable with polarizing control component, the detector arrangement is used to detect the output power of main amplifier,
And change the attenuator changed in polarizing control component according to output power, to carry out negative-feedback regu- lation.
5. a kind of multipolarization Microwave emission method, which comprises the steps of:
S1 carries out power distribution to input signal, is divided into four road signals, the amplitude and phase of the road Bing Duimei signal are adjusted；
S2 is transmitted the every road signal adjusted through amplitude and phase；
S3 amplifies processing to received signal；
Received two-way is synthesized M signal all the way through the signal of enhanced processing and is transmitted by S4；
All M signals are synthesized transmitting signal by S5；
The S1 includes the following steps:
S11 carries out power distribution to input signal, is divided into four road signals, the road Bing Jiangmei signal is transmitted；
S12 is classified into the four road road signal Zhong Mei signals and carries out a phase adjustment；
S13 carries out power compensation to the signal through a phase adjustment；
Signal through power compensation is carried out amplitude adjustment by S14；
Amplitude adjusted signal is amplified processing by S15；
Further include the steps that carrying out quadratic phase adjustment to the signal through a phase adjustment after the S12.
