AI Technical Summary
Traditional measurement and control systems introduce additional switching devices and attenuators in large dynamic control, which leads to a deterioration of the system's G/T value and makes it impossible to simultaneously meet the requirements of large dynamic signal reception and index maintenance.
A brand-new large dynamic field amplifier implementation method is adopted, including a sum-path digitally controlled field amplifier unit, a differential-path digitally controlled field amplifier unit, a sum-path gain compensation unit, a differential-path gain compensation unit, and an attenuation control unit. The signal consistency is ensured through a synchronous control mechanism, and the field amplifier uses built-in digitally controlled attenuator and latch technology.
It achieves the goal of maintaining the system's G/T value without deterioration during high dynamic range signal reception, ensuring the level and phase consistency of the sum and difference signals, and is suitable for normal reception tasks of the transmission first zone telemetry and control system.
