BIPOLAR ANALOG INTEGRATED CIRCUIT

µPC8002

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 power-

off 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
