COLLINS 204C-1

GENERAL DESCRIPTION

204C-1 10 KW POWER AMPLIFIER

A manually tuned linear power amplifier capable of 10 kw output over the 4 to 25 mc frequency range. A nominal 0.1 watt drive signal at the desired output frequency is supplied by an external source.

May be used in continuous duty applications with either attended or unattended operation. Local or remote control may be employed.

Phase detectors which provide an accurate resonance indication facilitate tuning. A 4CX5000A ceramic-seal tetrode is used as the output amplifier.

Accurate neutralization is maintained over the entire frequency range by a broadband capacitance bridge circuit. A pi-L output network provides very high harmonic attenuation in the final amplifier.

Power amplifier tuning and loading controls have very low inter-action.
