In addition the IC provides a prestage control and an IF post amplification. The IC is especially suitable for use in car radios with prestage control and distributed IF-selection. The integrated circuit includes an 2-pin oscillator with symmetrical input, buffered output and a double balanced mixer for frequency conversion. The RF-input stage allows symmetrical and unsymmetrical operation. The resulting IF is amplified in a first linear IF-driver with adjustable gain and in a second IF-driver with an adjustable temperature coefficient. Between these drivers an additional IF-selection is recommended. The AGC-stage integrated for prestage control can drive PIN-Diodes as well as MOSFET's. The IC also includes a reference voltage source with high supply voltage ripple rejection.
