GaAs INTEGRATED CIRCUIT
PG154TB
L-BAND SPDT SWITCH
DESCRIPTION
The PG154TB is an L-band SPDT (Single Pole Double Throw) GaAs FET switch which was developed for digital cellular or cordless telephone application. The device can operate from 100 MHz to 2.5 GHz, having the low insertion loss. It housed in an original 6-pin super minimold package that is smaller than usual 6-pin minimold easy to install and contributes to miniaturizing the system.
FEATURES
* Low Insertion Loss : LINS = 0.65 dB TYP. @VCONT = +3.0 V/0 V, VDD = +3.0 V, CX = 2.0 pF, f = 2 GHz * High Power Switching : Pin (1 dB) = +30 dBm TYP. @VCONT = +3.0 V/0 V, VDD = +3.0 V, CX = 2.0 pF, f = 2 GHz * Small 6-pin super minimold package (Size: 2.0 x 1.25 x 0.9 mm)
APPLICATIONS
* L, S-band digital cellular or cordless telephone * PCS, WLAN and WLL applications
ORDERING INFORMATION
Part Number Marking G1K Package 6-pin super minimold Supplying Form Embossed tape 8 mm wide. Pin 1, 2, 3 face to tape perforation side. Qty 3 kp/reel.
PG154TB-E3
Remark To order evaluation samples, please contact your local NEC sales office. (Part number for sample order: PG154TB)
Caution The IC must be handled with care to prevent static discharge because its circuit is composed of GaAs MES FET.

Note Pin (1 dB) and Pin (0.1 dB) are measured the input power level when the insertion loss increase more 1 dB or 0.1 dB than that of linear range. All other characteristics are measured in linear range. Cautions 1. The value of trap capacitor to improve the isolation performance should be chosen to accommodate the operating frequency, band width, switching speed and the condition with actual board of your system. The distance between IC's No.2 pin and trap capacitor CX should be placed as shorter as possible to avoid parasitic parameters. 2. When the PG154TB is used, it is necessary to use DC blocking capacitors for No.1 (OUT1), No.3 (OUT2) and No.5 (IN). The value of DC blocking capacitors should be chosen to accommodate the operating frequency, band width, switching speed and the condition with actual board of your system. The range of recommended DC blocking capacitor value is less than 100 pF.

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: Aircraft, 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.
