BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC8001
IF AMPLIFIER IC
WITH ON-CHIP MIXER FOR DIGITAL CELLULAR PHONES
The µPC8001 is a 3-volt IF am plifier IC with an on-chip m ixer developed for digital cellular phones.
The µPC8001 consists of a high-sensitivity lim iter am plifier with an input frequency of 455 kHz, a high-speed
and high-precision linear RSSI (received signal strength indicator ), and a second m ixer with an input frequency
of 80 to 150 MHz.
The µPC8001 features a low 3 m A (TYP.) and 2.2 µA (TYP.) current consum ption at norm al operation and
power-OFF, respectively. Its high-speed charge/discharge circuit enables fast power-ON/OFF switching.
The µPC8001 boasts an extrem ely sm all size packaged in a 14-pin plastic shrink SOP, and low external
capacitances of less than 0.01 µF, in addition to an on-chip RSSI output resistor, and is m ost suitable for
high-density m ounting.
