Compact, low noise amplifier focuses on cellular Infrastructure applications

Avago Technologies has unveiled the latest addition to its family of ultra low noise, high gain, high linearity Gallium Arsenide (GaAs) active bias amplifiers for use in cellular infrastructure applications.

Avago's MGA-633P8, which is an easy-to-use GaAs monolithic microwave IC (MMIC) low noise amplifier (LNA), claims to provide 'Best in Class' performance and has a compact footprint. Additionally, it has a common printed circuit board layout, which is ideal for front-end applications used in cellular base stations. The MGA-633P8 is designed to be used as a first stage LNA for cellular base station transceiver radio cards, tower mounted amplifiers, combiners, repeaters and remote/digital radio heads.

The MGA-633P8 uses Avago's proprietary GaAs Enhancement-mode pHEMT process to achieve such a high gain with a very low noise figure. Housed in a compact 2.0 mm by 2.0 mm by 0.75 mm 8-pin Quad-Flat-Non-Lead (QFN) package, the MGA-633P8 is designed to enable cellular applications that operate within the 450 to 2000 MHz frequency range to achieve superior performance levels. As a result, designers will be able to use this active bias LNA to develop next-generation cellular applications that are more compact with more features and functions to satisfy the growing needs of designers. With its compact low-profile footprint coupled with its low noise, high gain and high linearity features the MGA-633P8 is an ideal choice for use in line terminal equipment, GSM, CDMA, WCDMA, CDMA2000 and TD-SCDMA cellular infrastructure applications.

Features include:

  • Ultra-low noise figure: 0.37 dB
  • High linearity performance
  • 18 dB gain
  • Input return loss: 15 dB
  • 37 dBm output IP3
  • 22 dBM output power at 1 dB gain compression.
  • Tape-and-reel packaging option available

  • Pb-Free and RoHS compliant

Availability and Pricing

Avago's MGA-633P8 LNA is priced at $2.31 each in 10,000 piece quantities. Samples and production quantities are available now through Avago's direct sales channel and worldwide distribution partners.
