DESCRIPTION
GENERAL DESCRIPTION
The UAA2080 is a high-performance low-power radio
receiver circuit primarily 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 receiver 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.
Two complete signal paths with signals of 90 phase
difference are required to demodulate the signal.
All channel selectivity is provided by the built-in IF filters.
The circuit makes extensive use of on-chip capacitors to
minimize the number of external components.
The UAA2080 was designed to operate together with the
PCA5000A, PCF5001 or PCD5003 POCSAG decoders,
which contain a digital input filter for optimum call success
rate.
