The ease-of-use and extended broadband performance of Avago’s MGA-30×89 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.
