| Abstract: |
| The realization of microwave large dynamic range control for the first zone TT&C station in manned space flight TT&C and communication system is introduced. Adopting the "two states" intermittent and automatic control scheme and using high performance large dynamic range control modules, 96 dB large dynamic range control is achieved, as well as anti-strong-signal- intermodulation,high sensitivity receiving and the consistency between the phase and gain of sum and difference channels. |
