UPC8002

DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µPC8002 SECOND MIXER + IF AMPLIFIER FOR DIGITAL CORDLESS TELEPHONES The µPC8002 is a monolithic IC developed for use in digital cordless telephones. Its internal equivalent circuits comprise a double balanced mixer (DBM), IF amplifier circuit, and RSSI (Received Signal Strength Indicator) circuit. The µPC8002 can operate on a wide range of power supply voltages from 2.7 V to 5.5 V, and incorporates a poweroff function, making it ideal for achieving low set power consumption. The package is a 20-pin plastic shrink SOP (225 mil) suitable for high-density surface mounting. FEATURES Low-voltage, low-consumption-current operation possible (VCC = 2.7 to 5.5 V, ICC = 3.4 mA at VCC = 3 V) Wide mixer input frequency range (fMIX = 250 MHz (TYP.) to 500 MHz (MAX.)) Wide IF amplifier input frequency range (fIF = 8 MHz (MIN.) to 12 MHz (MAX.), 10.7 MHz (TYP.)) High limiting sensitivity (SL = –100 dBm (TYP.)) Wide RSSI dynamic range (DR = 85 dB (TYP.)) On-chip power-off function Use of 20-pin plastic shrink SOP (225 mil) allows high-density surface mounting BLOCK DIAGRAM GND VCC BYPASS3 (IF OUT) (IF OUT) IF2 OUT 14 13 12 11 BYPASS1 IF1 IN 20 19 BYPASS2 IF1 OUT BYPASS4 IF2 IN 18 17 16 15 IF Amp 1 IF Amp 2 Output Stage Power ON/OFF 2nd MIXER RSSI RSSI 1 2 3 4 5 6 7 8 9 10 PD MIX OUT VCC (IF) VCC (MIX) LO IN GND(IF) GND(MIX) MIX IN1 MIX IN2 RSSI OUT ORDERING INFORMATION Part Number Package 20-pin plastic shr...
