Overview

2kw 3.9GHz state power source  is mainly consisting of six parts, power amplifier (PA) unit, central control unit (CCU), power supply control unit (PSCU), switching mode power supply (SMPS), passive components (divider, combiner,waveguide , directional coupler, etc.) and cooling system. 

Features

1.The whole machine adopts high-efficiency and energy-saving design: the power amplifier module RF circuit of the whole machine adopts DOHERTY technology, and the whole machine distribution and synthesis are all one-time distribution and synthesis methods, with minimal insertion loss and cable loss in the entire RF channel

2. High reliability redundancy design of the whole machine: redundant design of the main and backup dual cooling systems, low noise, stable and reliable; The centrifugal fan in the cooling system can be maintained and replaced online without stopping the machine.

3. Reliability and quality assurance of power amplifier: The power amplifier PCB board adopts the exclusive domestic process technology of direct welding with the copper pad, which greatly reduces the RF circuit loss, fully ensures the efficient heat dissipation of the power tube, and effectively guarantees the long-term stable and reliable working environment conditions of the power tube.

4. Multi functional and high performance guarantee design of exciter: The exciter has online linear and nonlinear real-time adaptive pre correction function; And it has the functions of stream detection and reorganization, suitable for single frequency network and multi frequency network operation under various condition
