DATA SHEET GaAs INTEGRATED CIRCUIT µPG181GR GaAs MMIC DBS Twin IF Switch DESCRIPTION The µPG181GR is intended for use in Direct Broadcast Satellite (DBS) applications within the Low Noise Block (LNB) down-converter for systems where at least two LNB outputs are required. It offers two intermediate frequency amplifier channels that can independently select 1 of 2 IF inputs. It is loused in a very small 16-pin plastic HTSSOP package available on tape-and-reel and easy to install and contributes to miniaturizing the systems. FEATURES • Two Independent IF Channels • Integral Switching to Channel Input to Either Channel Output • Insertion Loss Per Channel : 5.0 dB TYP. (ZO = 50 Ω) • Frequency Range : 950 MHz to 2 150 MHz • Channel to Channel Isolation : 33 dB TYP. • Small 16-pin HTSSOP Package ORDERING INFORMATION (PLAN) Part Number µPG181GR-E1 Package Supplying Form 16-pin Plastic HTSSOP Carrier tape width 12 mm.

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. M7 98. 8
