BIPOLAR ANALOG INTEGRATED CIRCUITS µµµµPC8119T, µµµµPC8120T VARIABLE GAIN AMPLIFIER SILICON MMIC FOR TRANSMITTER AGC OF DIGITAL CELLULAR TELEPHONE 1996 © Document No. P11027EJ2V0DS00 (2nd edition) Date Published October 1998 N CP(K) Printed in Japan DATA SHEET The mark shows major revised points. DESCRIPTION The µPC8119T and µPC8120T are silicon monolithic integrated circuits designed as variable gain amplifier. Due to 100 MHz to 1.9 GHz operation, these ICs are suitable for RF transmitter AGC stage of digital cellular telephone. Two types of gain control let users choose in accordance with system design. 3 V supply voltage and mini mold package contribute to make system lower voltage, decreased space and fewer components. The µPC8119T and µPC8120T are manufactured using NEC’s 20 GHz fT NESATTM 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 • Recommended operating frequency : f = 100 MHz to 1.92 GHz • Supply voltage : VCC = 2.7 to 3.3 V • Low current consumption : ICC = 11 mA TYP. @ VCC = 3.0 V • Gain control voltage : VAGC = 0.6 to 2.4 V (recommended) • Two types of gain control : µPC8119T = VAGC up vs. Gain down (Forward control) µPC8120T = VAGC up vs. Gain up (Reverse control) • AGC control can be constructed by external control circuit. • High-density surface mounting APPLICATIONS • 1.9 GHz cordless telephone (PHS base-station and so on) • 800 MHz to 900 MHz or 1.5 GHz Digital cellular telephone (PDC800M, PDC1.5G and so on) ORDERING INFORMATION Part Number Package Marking Supplying Form Gain Control Type µPC8119T-E3 C2M Forward control µPC8120T-E3 6-pin minimold C2N Embossed tape 8 mm wide. 1, 2, 3 pins face to perforation side of the tape. Qty 3 kp/reel. Reverse control Remark To order evaluation samples, please contact your local NEC sales office. (Part number for sample order: µPC8119T, µPC8120T) Caution Electro-static sensitive devices |
