Avago adds three new high linearity gain blocks for wireless infrastructure apps

SAN JOSE, USA & SINGAPORE: Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, announced the addition of three new innovative flat gain, high linearity low noise, gain blocks that can be used as a broadband gain block or radio frequency (RF) driver amplifier MMIC.

Housed in an industry standard SOT-89 package measuring 4.5mm by 4.1mm by 1.5 mm, Avago’s MGA-30x89 series now covers frequency bands from 40 to 6000MHz and only requires a simple DC biasing match. Moreover, no additional RF matching components are required to achieve wide bandwidth performance.

The ease-of-use and extended broadband performance of Avago’s MGA-30x89 series makes these gain blocks an ideal choice for designers of cellular devices, WiMAX wireless base stations, satellite and cable TV set-top boxes, and a variety of other wireless applications that operate within the 40 to 6000MHz frequency range.

The flat gain and high linearity features of these devices are achieved through the use of Avago’s proprietary 0.25 µm GaAs enhancement-mode pHEMT process. 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 also ideal for use in other cellular infrastructure designs that require the same driver amplifier or gain block for different frequencies.

Avago’s MGA-30789 and MGA-30889/30989 flat gain, high linearity gain blocks are available now with pricing starting from $1.69 and $1.25, respectively in 10,000 unit volumes.
