Gain block also works as a driver amplifier MMIC

The MGA-30689 operates in the 40 to 2,600MHz frequency band and only requires a simple DC biasing match.

No additional RF matching components are required to achieve wide-bandwidth performance.

The ease-of-use and broadband performance of the MGA-30689 make it ideal for designers of cellular devices, Wimax wireless base stations, satellite and cable set-top boxes and a variety of other wireless applications that operate in the 40 to 2,600MHz frequency range.

Avago's 0.25um GAAS enhancement-mode pHEMT process helps to achieve the flat gain and high linearity features of this device.

The built-in temperature-compensated internal bias circuit also provides stable current over-temperature and process threshold voltage variations.

Additionally, the broadband flat-gain feature is suitable for use in other cellular infrastructure designs that require the same driver amplifier or gain block for different frequencies.

At a typical operating condition of 5V and 103mA, the MGA-30689 delivers performance of 14dBm gain, 40dBm OIP3 and 22dBm P1dBm and 3.2dBm noise figure at 1,950MHz.

It is housed in an industry-standard SOT-89 package measuring 4.5 x 4.1 x 1.5mm.

Avago will demonstrate its latest amplifiers at the 2009 IEEE MTT-S International Microwave Symposium, to be held at the Boston (MA) Convention and Exhibition Center.
