WIDEBAND FM IF
SUBSYSTEM FOR PHS
AND DIGITAL
The MC13159 is a wideband FM IF subsystem that is designed for high
performance data and digital applications. Excellent high frequency
performance is achieved, with low cost, through the use of Motorola’s RF
bipolar process. The MC13159 includes a mixer, local oscillator buffer
amplifier, IF amplifier, limiter amplifier and RSSI functions. The mixer is
useful for a 240 MHz input used in a single–ended/balanced differential
configuration. The IF and limiter amplifier are separated so that an external
filter can be used in series, or connected directly with an external capacitor.
The RSSI output is derived by summing the output of both the IF and
Limiter sections. An enable control is provided to power down the IC for
power management in battery powered applications.
APPLICATIONS
SEMICONDUCTOR
TECHNICAL DATA
