ORDERING INFORMATION TYPE NUMBER UAA2082H UAA2082U PACKAGE NAME LQFP32 28 pads naked die; see Fig.8 DESCRIPTION plastic low profile quad flat package; 32 leads; body 7 × 7 × 1.4 mm GENERAL DESCRIPTION UAA2082 The UAA2082 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 complet...
