CA3012
Wideband Amplifier
CA3012 wideband amplifier with limiter gain stages bipolar monolithic technology. input open base separate feedback bias. feedback bias pin, BYPASS, externally bypassed provides means tuned coil input pin. output high impedance open collector which matched tuned transformer, driving detector. Internal regulation circuits provide bias gain stages feedback circuit. CA3012 intended limiting applications requiring high gain.
