The ML13158 is a wideband IF subsystem that is designed for high performance data and analog applications. The ML13158 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 a 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. A precision data shaper has an Off function to shut the output off to save current. An enable control is provided to power down the IC for power management in battery operated applications.

APPLICATIONs include DECT, wideband wireless data links for personal and portable laptop computers and other battery operated radio systems which utilize GFSK, FSK or FM modulation.
