DATA SHEET BIPOLAR ANALOG INTEGRATED CIRCUIT µPC8001 IF AMPLIFIER IC WITH ON-CHIP MIXER FOR DIGITAL CELLULAR PHONES The µPC8001 is a 3-volt IF amplifier IC with an on-chip mixer developed for digital cellular phones. The µPC8001 consists of a high-sensitivity limiter amplifier with an input frequency of 455 kHz, a high-speed and high-precision linear RSSI (received signal strength indicator ), and a second mixer with an input frequency of 80 to 150 MHz. The µPC8001 Features a low 3 mA (TYP.) and 2.2 µA (TYP.) current consumption at normal operation and power-OFF, respectively. Its high-speed charge/discharge circuit enables fast power-ON/OFF switching. The µPC8001 boasts an extremely small 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 most suitable for high-density mounting.
