UAA3220T Datasheet

RF Receiver


The UAA3220T is a fully integrated single-chip receiver,primarily intended for use in VHF and UHF systems.It supports both Amplitude Shift Keying (ASK) andFrequency Shift Keying (FSK) demodulation.By connecting DEMO1 (pin 10) to ground duringrealisation of the receiver module the UAA3220TS worksas an ASK receiver (see Fig.10). By connecting pin 10 asshown in Fig.9 the UAA3220TS works as an FSK receiver.The UAA3220TS incorporates a crystal stabilized localoscillator, frequency multiplier, balanced mixer, post mixeramplifier, limiter, Received Signal Strength Indicator(RSSI), FSK demodulator, data filter, data slicer andpower down circuit. UAA3220T Features • Low cost single-chip ASK or FSK receiver• Superheterodyne architecture with high integration level• Few external low cost components and crystal required• Wide supply voltage range• Low power consumption• Wide frequency range, 250 to 920 MHz• High sensitivity• IF bandwidth determined by application• High selectivity• Automotive temperature range• SSOP24 package. UAA3220T Applications • Keyless entry systems• Car alarm systems• Remote control systems• Security systems• Telemetry systems• Wireless data transmission• Domestic appliance
