The BT10381P is a fully integrated, high-performance, low-power, CMOS monolithic RF receiver designed specifically for wide area digital paging systems. The BT10381P employs a direct FM Non-Return-to-Zero (NRZ) Frequency Shift Keying (FSK) digital demodulation scheme. The receiver design is based on dual conversion of the input RF signal to the baseband signal by on-chip mixers. The BT10381P includes an on-chip RF Downconversion Mixer, IF Downconversion Mixer, Limiter/RSSI block, Digital FSK Demodulator, FSK Reference PLL, a low battery indicator, and an on-chip +1V Regulator. The BT10381P requires a DC supply voltage of +2.7V. |
