BIPOLAR ANALOG INTEGRATED CIRCUIT
µPC8112TB
SILICON MMIC 1st FREQUENCY DOWN-CONVERTER
FOR CELLULAR/CORDLESS TELEPHONE
DESCRIPTION
The µPC8112TB is a silicon monolithic integrated circuit designed as 1st frequency down-converter for
cellular/cordless telephone receiver stage. This IC consists of mixer and local amplifier. The µPC8112TB features
high impedance output of open collector. Similar ICs of the µPC2757TB and µPC2758TB feature low impedance
output of emitter follower. These TB suffix ICs which are smaller package than conventional T suffix ICs contribute to
reduce your system size.
The µPC8112TB is manufactured using NEC’s 20 GHz fT NESAT™III silicon bipolar process. This process uses
silicon nitride passivation film and gold electrodes. These materials can protect chip surface from external pollution
and prevent corrosion/migration. Thus, this IC has excellent performance, uniformity and reliability.
FEATURES
• Excellent RF performance : IIP3 = –7 dBm@fRFin = 1.9 GHz (reference)
IM3 = –88 dBc@PRFin = –38 dBm, 1.9 GHz (reference)
• Similar conversion gain to µPC2757 and lower noise figure than µPC2758
• Minimized carrier leakage : RFIo = –80 dB@fRFin = 900 MHz (reference)
RFIo = –55 dB@fRFin = 1.9 GHz (reference)
• High linearity
: PO (sat) = –2.5 dBm TYP.@fRFin = 900 MHz
PO (sat) = –3 dBm TYP.@fRFin = 1.9 GHz
• Low current consumption
: ICC = 8.5 mA TYP.
• Supply voltage
: VCC = 2.7 to 3.3 V
• High-density surface mounting : 6-pin super minimold package
APPLICATIONS
• 1.5 GHz to 1.9 GHz cellular/cordless telephone (PHS, DECT, PDC1.5G and so on)
• 800 MHz to 900 MHz cellular telephone (PDC800M and so on)
