Design of dual-channel circuit of P-band instantaneous polarization radar

First of all, the detection theory of the instantaneous polarization radar is introduced. The overall structure of dual-channel circuit has been designed. The principle part of RF system consists of antenna arrays and the dual-channel receiving and transmitting circuit. Si4133 chip used as the core design of the high stability, fully coherent frequency synthesizer as instantaneous polarization radar´s frequency source. Then the structural design of inverters pieces is discussed, clear frequency convert program is reasonable. ADEX-10L devices use to produce high vibration isolation mixers. The dual-channel receiver components focuses on the development of voltage-controlled gain amplifier based on the AD8367 chip, and the amplitude-frequency characteristics, phase frequency characteristics and dual-channel consistency were tested. The introduction of the automatic power balance technology to ensure that the two-channel transmitter power balance.
