PG154TB

L-BAND SPDT SWITCH

DESCRIPTION

The µPG154TB 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 : L

• High Power Switching: P

• Small 6-pin super minimold package (Size: 2.0 × 1.25 × 0.9 mm)

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 C
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),

µµµµ

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.

Caution

The Great Care must be taken in dealing with the devices in this guide.
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.

consent of NEC Corporation. NEC Corporation assumes no responsibility for any errors which may appear in
this document.

• NEC Corporation does not assume any liability for infringement of patents, copyrights or other intellectual property
rights of third parties by or arising from use of a device described herein or any other liability arising from use
of such device. No license, either express, implied or otherwise, is granted under any patents, copyrights or other
intellectual property rights of NEC Corporation 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 the customer's equipment shall be done under the full responsibility
of the customer. NEC Corporation assumes no responsibility for any losses incurred by the customer or third
parties arising from the use of these circuits, software, and information.

• 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: 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.
