µ
PC8001
IF AMPLIFIER IC
WITH ON-CHIP MIXER FOR DIGITAL CELLULAR PHONES
The
µ
PC8001 is a 3-volt IF amplifier IC with an on-chip mixer developed for digital cellular phones.
The
µ
PC8001 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
µ
PC8001 features a low 3 mA (TYP.) and 2.2
µ
A (TYP.) current consumption at normal operation and
power-OFF, respectively. Its high-speed charge/discharge circuit enables fast power-ON/OFF switching.
The
µ
PC8001 boasts an extremely small size packaged in a 14-pin plastic shrink SOP, and low external
capacitances of less than 0.01
µ
F, in addition to an on-chip RSSI output resistor, and is most suitable for
high-density mounting.
