Avago Introduces Innovative Flat Gain High Linearity Gain Block for Cellular, WiMAX and Set-Top Boxes
Avago Technologies has announced a new innovative flat gain, high linearity low noise gain block that can be used as either a broadband gain block or driver amplifier MMIC. Housed in an industry standard SOT-89 package measuring 4.5mm by 4.1mm by 1.5 mm, Avago’s MGA-30689 flat gain, high linearity gain block operates in the 40 to 2,600 MHz frequency band and only requires a simple DC biasing match.
Moreover, no additional RF matching components are required to achieve wide bandwidth performance. Avago is a leading supplier of analog interface components for communications, industrial and consumer applications.
The ease-of-use and broadband performance of the MGA-30689 makes it an ideal choice for designers of cellular devices, WiMAX wireless base stations, satellite and cable TV set-top boxes, as well as a variety of other wireless applications that operate within the 40 to 2,600 MHz frequency range. The flat gain and high linearity features of this device is 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 great 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 1,950 MHz.
