BIPOLAR ANALOG INTEGRATED CIRCUIT µµµµPC8112TB SILICON MMIC 1st FREQUENCY DOWN-CONVERTER FOR CELLULAR/CORDLESS TELEPHONE © 1997, 2000 Document No. P12808EJ2V0DS00 (2nd edition) Date Published June 2000 N CP(K) Printed in Japan DATA SHEET The mark shows major revised points. 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) ORDER INFORMATION Part Number Package Markings Supplying Form µPC8112TB-E3 6-pin super minimold C2K Embossed tape 8 mm wide. Pin 1, 2, 3 face the tape perforation side. Qty 3kpcs/reel. Remark To order evaluation samples, please contact your local NEC sales office.
