| DATA SHEET PC2791TB, PC2792TB 5 V, SUPER MINIMOLD SILICON MMIC VHF-UHF WIDEBAND AMPLIFIER BIPOLAR ANALOG INTEGRATED CIRCUITS DESCRIPTION The PC2791TB and PC2792TB are silicon monolithic integrated circuits designed as 2nd IF buffer amplifier for DBS tuners. Among the 6-pin mini/super minimold amplifiers, PC2791TB and PC2792TB have unique pin locations taken over from conventional 4-pin minimold PC1675G, PC1676G and PC1688G. These ICs are manufactured using NEC's 10GHz fT NESATTM II AL silicon bipolar process. This process uses silicon nitride passivation film. The material can protect chip surface from external pollution and prevent corrosion/migration. Thus, these IC have excellent performance, uniformity and reliability.

CAPACITORS FOR THE VCC, INPUT AND OUTPUT PINS 1 000 pF capacitors are recommendable as bypass capacitor for VCC pin and coupling capacitors for input/output pins. Bypass capacitor for VCC pin is intended to minimize VCC pin's ground impedance. Therefore, stable bias can be supplied against VCC fluctuation. Coupling capacitors for input/output pins are intended to minimize RF serial impedance and cut DC. To get flat gain from 100 MHz up, 1 000 pF capacitors are assembled on the test circuit. [Actually, 1 000 pF capacitors give flat gain at least 10 MHz. In the case of under 10 MHz operation, increase the value of coupling capacitor such as 2 200 pF. Because the coupling capacitors are determined by the equation of C = 1/(2 fZs).] 6 Data Sheet P11863EJ3V0DS PC2791TB, PC2792TB ILLUSTRATION OF THE TEST CIRCUIT ASSEMBLED ON EVALUATION BOARD AMP-3 Top View 1 2 3 S C2 IN C C OUT Mounting direction (Marking is an example for PC2791TB) C COMPONENT LIST Value C 1 000 pF For more information on the use of this IC, refer to the following application note: USAGE AND APPLICATIONS OF 6-PIN MINI-MOLD, 6-PIN SUPER MINI-MOLD SILICON HIGH-FREQUENCY WIDEBAND AMPLIFIER MMIC (P11976E). 6 5 4 VCC Notes 1. 30 x 30 x 0.4 mm double sided copper clad polyimide board. 2.

(2) Form a ground pattern as widely as possible to minimize ground impedance (to prevent undesired oscillation). All the ground pins must be connected together with wide ground pattern to decrease impedance difference. (3) The bypass capacitor should be attached to VCC line. (4) The DC cut capacitor must be each attached to input pin and output pin. RECOMMENDED SOLDERING CONDITIONS This product should be soldered under the following recommended conditions. For soldering methods and conditions other than those recommended below, contact your NEC sales representative. Soldering Method Infrared Reflow Soldering Conditions Package peak temperature: 235 C or below Time: 30 seconds or less (at 210 C) Count: 3, Exposure limit: NoneNote Package peak temperature: 215 C or below Time: 40 seconds or less (at 200 C) Count: 3, Exposure limit: NoneNote Soldering bath temperature: 260 C or below Time: 10 seconds or less Count: 1, Exposure limit: NoneNote Pin temperature: 300 C or below Time: 3 seconds or less (per side of device) Exposure limit: NoneNote Recommended Condition Symbol IR35-00-3 VPS VP15-00-3 Wave Soldering WS60-00-1 Partial Heating - Note After opening the dry pack, keep it in a place below 25 C and 65% RH for the allowable storage period.

The information is subject to change without notice. For actual design-in, refer to the latest publications of NEC's data sheets or data books, etc., for the most up-to-date specifications of NEC semiconductor products. Not all products and/or types are available in every country. Please check with an NEC sales representative for availability and additional information. * No part of this document may be copied or reproduced in any form or by any means without prior written consent of NEC. NEC assumes no responsibility for any errors that may appear in this document. * NEC does not assume any liability for infringement of patents, copyrights or other intellectual property rights of third parties by or arising from the use of NEC semiconductor products listed in this document or any other liability arising from the use of such products. No license, express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC or others. * Descriptions of circuits, software and other related information in this document are provided for illustrative purposes in semiconductor product operation and application examples. The incorporation of these circuits, software and information in the design of customer's equipment shall be done under the full responsibility of customer. NEC assumes no responsibility for any losses incurred by customers or third parties arising from the use of these circuits, software and information. * While NEC endeavours to enhance the quality, reliability and safety of NEC semiconductor products, customers agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize risks of damage to property or injury (including death) to persons arising from defects in NEC semiconductor products, customers must incorporate sufficient safety measures in their design, such as redundancy, fire-containment, and anti-failure features. * NEC semiconductor products are classified into the following three quality grades: "Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products developed based on a customer-designated "quality assurance program" for a specific application. The recommended applications of a semiconductor product depend on its quality grade, as indicated below. Customers must check the quality grade of each semiconductor product before using it in a particular application. "Standard": Computers, office equipment, communications equipment, test and measurement equipment, audio and visual equipment, home electronic appliances, machine tools, personal electronic equipment and industrial robots "Special": Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster systems, anti-crime systems, safety equipment and medical equipment (not specifically designed for life support) "Specific": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems and medical equipment for life support, etc. The quality grade of NEC semiconductor products is "Standard" unless otherwise expressly specified in NEC's data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness to support a given application. (Note) (1) "NEC" as used in this statement means NEC Corporation and also includes its majority-owned subsidiaries. (2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for NEC (as defined above). M8E 00. 4 |
