Wideband FM IF Subsystem
MC13158
The MC13158 is a wideband IF subsystem that is designed for high performance data and analog applications. Excellent high frequency performance is achieved, with low cost, through the use of Motorola’s MOSAIC 1.5™ RF bipolar process. The MC13158 has an on–board grounded collector VCO transistor that may be used with a fundamental or
overtone crystal in single channel operation or with a PLL in multi–channel operation. The mixer is useful to 500 MHz and may be used in a balanced differential or single ended configuration. The IF amplifier is split to accommodate two low cost cascaded filters. RSSI output is derived by summing the output of both IF sections.
