Product Summary
The UAA2082H is an advanced pager receiver. It is intended for VHF, UHF and 900 MHz pager receivers for wide area digital paging systems, employing direct FM non-return-to-zero (NRZ) frequency shift keying (FSK). The UAA2082H design is based on the direct conversion principle where the input signal is mixed directly down to the baseband by a local oscillator on the signal frequency. The applications of the UAA2082H include: Wide area paging, On-site paging, Telemetry, RF security systems, Low bit-rate wireless data links.
