BIPOLAR ANALOG INTEGRATED CIRCUITS µµµµPC2757TB, µµµµPC2758TB SILICON MMIC 1st FREQUENCY DOWN-CONVERTER FOR CELLULAR/CORDLESS TELEPHONE Document No. P12771EJ2V0DS00 (2nd edition) Date Published June 2000 N CP(K) Printed in Japan DATA SHEET © 1997, 2000 The mark shows major revised points. DESCRIPTION The µPC2757TB and µPC2758TB are silicon monolithic integrated circuit designed as 1st frequency down- converter for cellular/cordless telephone receiver stage. The ICs consist of mixer and local amplifier. The µPC2757TB features low current consumption and the µPC2758TB features improved intermodulation. From these two version, you can chose either IC corresponding to your system design. These TB suffix ICs which are smaller package than conventional T suffix ICs contribute to reduce your system size. The µPC2757TB and µPC2758TB are manufactured using NEC’s 20 GHz fT NESAT™||| 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 • Wideband operation : fRFin = 0.1 to 2.0 GHz, fIFin = 20 to 300 MHz • High-density surface mounting : 6-pin super minimold package • Low current consumption : ICC = 5.6 mA TYP. @ µPC2757TB ICC = 11 mA TYP. @ µPC2758TB • Supply voltage : VCC = 2.7 to 3.3 V • Minimized carrier leakage : Due to double balanced mixer • Equable output impedance : Single-end push-pull IF amplifier • Built-in power save function APPLICATIONS • Cellular/cordless telephone up to 2.0 GHz MAX. (example: GSM, PDC800M, PDC1.5G and so on): µPC2758TB • Cellular/cordless telephone up to 2.0 GHz MAX. (example: CT1, CT2 and so on): µPC2757TB ORDERING INFORMATION Part Number Package Markings Supplying Form Product Type µPC2757TB-E3 C1X Low current consumption µPC2758TB-E3 6-pin super minimold C1Y Embossed tape 8 mm wide.
