The TBA750CQ is a limiter/amplifier with an f.m. detector, d.c. volume control and a.f. preamplifier. It is intended for 4.5MHz, 5.5MHz, or 10MHz. The limiter/amplifier is a four-stage differential amplifier that gives very good noise and interference suppression. The detector is of the balanced type. The d.c. volume control stage has excellent control characteristics with a control range of more than 80dB.The a.f. preamplifier can drive a triode-pentode output stage or a class-A push-pull transistor output stage.
