Avago Technologies has announced four new gain block solutions that feature high linearity, high gain, excellent gain flatness and low power dissipation. The performance of the MGA-31189 and MGA-31289 0,25 Watt and MGA-31389 and MGA-31489 0,10 Watt gain blocks is made possible by Avago’s proprietary, 0,25 μm GaAs Enhancement-mode pHEMT semiconductor process.
The power amplifier family is optimised for frequency in order to perform across major cellular frequency bands. A common footprint and PCB layout allows a single design to support multiple frequencies and geographic markets with a choice of output power. The devices feature high gain which can reduce the total number of RF stages needed. The MGA-31189 and MGA-31389 serve applications from 50 MHz to 2,0 GHz and the MGA-31289 and MGA-31489 from 1,5 GHz to 3,0 GHz.
