1) DOUBLE SHIELDED RACK CONSTRUCTION
Internal heat is water-cooled and discharged outside
by self-contained heat exchanger.
Double-layer housing provides high RF/EMI shielding
performance.

2) WILKINSON RADIAL COMBINER
Single-stage power combining of output transistors
protected by each respective ferrite circulator provides
high reliability in long-term operation.
3) BROADCAST-TRANSMITTER-LEVEL REDUNDANCYHigh redundancy design of power supplies provides
fault-tolerant and sustainable system operation.
4) PASSIVE ANALOG PRE-DISTORTION
Very ideal AB-class linear power amplifier is realizedby passive analog predistortion circuit despite poor
linearity of LD-MOS transistor.

5) MULTIPLE CPU CONTROLLER AND SENSORS
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.
6) ADVANCED ANALOG RF POWER TECHNOLOGY
Short-term (1sec) phase stability in free-running operation
is within 0.1deg and RF voltage level stability is 0.1%.
