Characteristic for reference at 2.0 to 2.5 GHz. 2. Pin (1 dB) is measured the input power level when the insertion loss increase more 1 dB than that of linear range. All other characteristics are measured in linear range. NOTE ON CORRECT USE • Insertion loss and isolation of the IN-OUT2 is better than that of IN-OUT1, because No. 7 pin (OUT1) is placed to same side of No. 5 pin (IN). • The distance between IC’s GND pins and ground pattarn of substrate should be as shorter as possible to avoid parasitic parameters. 3 PPG138GV [PPG138GV] TEST BOARD IN 0.9 mm width 0.4 mm thickness teflon glass R = 50 Ω NEC G130/131 OUT1 R R VCONT1 VCONT2 Using the same board that of µPG130/131G OUT2 TEST CIRCUIT 50 Ω VCONT2 = 0 V/–3 V 1000 pF OUT2 ZO = 50 Ω 50 Ω 1 8 2 7 3 6 4 5 OUT1 ZO = 50 Ω IN ZO = 50 Ω 4 1000 pF VCONT1 = –3 V/0 V PPG138GV [PPG138GV] TRUTH TABLE OF SWITCHING BY CONDITION OF CONTROL VOLTAGE VCONT1 ð3 V 0V VCONT2 0V OUT1 IN OUT1 IN OUT2 OUT2 ð3 V IN OUT1 IN OUT1 OUT2 OUT2 PACKGE DIMENSIONS 8-PIN PLASTIC SHRINK SOP (175 mil) (Unit mm) 8 5 3˚ +7˚ –3˚ Detail of lead end 1 4 4.94 ± 0.2 3.0 MAX 0.1 ± 0.1 0.575 MAX 0.87 ± 0.2 0.15 +0.10 –0.05 1.8 MAX 1.5 ± 0.1 3.2 ± 0.1 0.5 ± 0.2 0.65 0.3 +0.10 –0.05 0.10 M 0.15 5 PPG138GV Floating the PPG138GV It is possible to use the PPG138GV with only a single +3 V supply by employing a technique known as “floating”. When the IC is floated using a +3 V supply, the voltage levels used to control the switch are elevated above ground by +3 V. When the PPG138GV is floated it is necessary to use DC blocking (C2, C3, C5) and grounding (C1, C4) capacitors. This enables the IC to isolated so that +3 V can be applied to RF line. The value for DC blocking capacitors should be chosen to accommodate the frequency of operation. Grounding capacitors are required to float the IC above ground. The value for grounding capacitor should be chosen to accommodate the frequency of operation. It is not recommended to float the PPG138GV for wide band application.

The reason is that the material of the devices is GaAs (Gallium Arsenide), which is designated as harmful substance according to the law concerned. Keep the law concerned and so on, especially in case of removal. No part of this document may be copied or reproduced in any form or by any means without the prior written consent of NEC Corporation.

No license, either express, implied or otherwise, is granted under any patents, copyrights or other intellectual property rights of NEC Corporation or others. While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices, the possibility of defects cannot be eliminated entirely. To minimize risks of damage or injury to persons or property arising from a defect in an NEC semiconductor device, customers must incorporate sufficient safety measures in its design, such as redundancy, fire-containment, and anti-failure features. NEC devices are classified into the following three quality grades: "Standard", "Special", and "Specific". The Specific quality grade applies only to devices developed based on a customer designated "quality assurance program" for a specific application. The recommended applications of a device depend on its quality grade, as indicated below. Customers must check the quality grade of each device 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: Aircrafts, aerospace equipment, submersible repeaters, nuclear reactor control systems, life support systems or medical equipment for life support, etc. The quality grade of NEC devices is "Standard" unless otherwise specified in NEC's Data Sheets or Data Books. If customers intend to use NEC devices for applications other than those specified for Standard quality grade, they should contact an NEC sales representative in advance. Anti-radioactive design is not implemented in this product. M4 96. 5
