300 Watts Exciter P.L.L. with Stereo Coder and RDS by hipro-tech.
Manufactured with the latest Transistor Mos-Fet technology, RD01MUS1 by Mitsubishi for driver Amplifier and MRF300BN by NXP, for final stage Amplifier.
RDS is "Locked" in phase with the Stereo's Coder 19Khz for avoiding "noises" in the main F.M. signal.
It "accepts" the 19KHz from Stereo Coder and with its internal Phase Lock Loop circuit, it "produces" its 57KHz in PHASE with the Stereo Coder's 19KHz.
Amplifier's temperature @ 300 Watts R.F. output power, is 7°C above environment's (though it has "small" heat sink), due to HIGH Efficient output transistor AND the "smart fins shape" of the newer fan design by DELTA.
The Amplifier is protected against reversed R.F. power at 70 Watts and from high temperature at 70°C.
The PSU is protected against high temperature at 70°C.
Its overall consumption from AC input is from 440 Watts to 470 Watts.
