HMC279MS8G v02.0701 GaAs MMIC DRIVER AMPLIFIER 2.5 - 4.2 GHz AMPLIFIERS - SMT 8 Typical Applications Features The HMC279MS8G is ideal for: High Gain: 36 dB • 2.6 - 2.7 GHz MMDS Psat Output Power: +14 dBm • 3.5 GHz Wireless Local Loop Single Supply: +3V @ 60 mA • 3.7 - 4.2 GHz Satellite (Receive and Transmit Bands) Ultra Small Package: MSOP8G Functional Diagram General Description No External Matching Required The HMC279MS8G is a +3V GaAs MMIC driver amplifier covering the 2.5 - 4.2 GHz frequency range. The device is packaged in a low cost, surface mount MSOP plastic package with an exposed base paddle for improved RF ground. The amplifier provides greater than 36dB gain and +14 dBm P1dB while operating from a single +3V supply at only 60mA. No external components are required and the amplifier occupies less than 0.023 sq. in. (14.6 sq. mm). All data is taken with the amplifier assembled into a 50 ohm test fixture with the exposed ground paddle connected to RF ground. Electrical Specifications, TA = +25° C, Vdd= +3V Parameter Min.

Signal lines should have 50 ohm impedance while the package ground leads and exposed paddle should be connected directly to the ground plane similar to that shown. A sufficient number of VIA holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request. *Circuit Board Material: Roger 4350 8-6 For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com v02.0701 HMC279MS8G GaAs MMIC DRIVER AMPLIFIER 2.5 - 4.2 GHz 8 AMPLIFIERS - SMT Notes: For price, delivery, and to place orders, please contact Hittite Microwave Corporation: 20 Alpha Road, Chelmsford, MA 01824 Phone: 978-250-3343 Fax: 978-250-3373 Order On-line at www.hittite.com 8-7
