描述 Description

GENERAL DESCRIPTION
The UAA3202M is a fully integrated single-chip receiver, primarily intended for use in VHF and UHF systems employing direct Frequency Shift Keying (FSK) modulation. The UAA3202M incorporates a SAW stabilized local oscillator, balanced mixer, IF amplifier, limiter, Received Signal Strength Indicator (RSSI), RSSI comparator, FSK demodulator, data filter and data slicer. The device features a power-down mode in order to minimize the average receiver supply current.FEATURES
? Low cost single-chip FSK receiver
? Superheterodyne architecture with high integration level
? Few external low cost components
? Wide supply voltage range
? Low power consumption
? Wide frequency range, 150 to 450 MHz
? High sensitivity
? IF band determined by application
? High selectivity
? Very low spurious radiation, ?60 dBm (meets FTZ 17TR2100)
? Automotive temperature range
? Power-down mode
? SSOP20 package.
