1) DOUBLE SHIELDED RACK CONSTRUCTION

2) WILKINSON RADIAL COMBINER

3) BROADCAST-TRANSMITTER-LEVEL REDUNDANCY

Internal heat is water-cooled and discharged outsideby self-contained heat exchanger. Double-layer housing provides high RF/EMI shieldingperformance.

Single-stage power combining of output transistorsprotected by each respective ferrite circulator provideshigh reliability in long-term operation.

High redundancy design of power supplies providesfault-tolerant and sustainable system operation.

Very ideal AB-class linear power amplifier is realizedby passive analog predistortion circuit despite poorlinearity of LD-MOS transistor.

Multiple CPUs monitor a total of 85 points and save thestatus data to an internal SD memory card by use ofModbus protocol and through Ethernet.

Short-term (1sec) phase stability in free-running operationis within 0.1deg and RF voltage level stability is 0.1%.

4) PASSIVE ANALOG PRE-DISTORTION

5) MULTIPLE CPU CONTROLLER AND SENSORS

6) ADVANCED ANALOG RF POWER TECHNOLOGY
