ABSTRACT:
Disclosed herein is a linear deflection amplifier which is suitable for processing horizontal sweep signals for driving a magnetic deflection yoke of a radar CRT PPI (Plan Position Indicator) display. The amplifier features a transadmittance feedback where output current follows input voltage. Flyback resonance is derived by a shunt capacitor coupled to an FET switch. Low cross-over distortion and temperature compensation of components within the system is achieved by use of a modified class B power MOSFET push-pull configuration.
