High Linearity, High Gain, Superior Gain Flatness in Industry Standard SOT-89 Package
SAN JOSE, Calif., and SINGAPORE- Avago Technologies (Nasdaq: AVGO), a leading supplier of analog interface components for communications, industrial and consumer applications, today announced four new Gain Block solutions that feature high linearity, high gain, excellent gain flatness and low power dissipation. The performance gains of the MGA-31189 and MGA-31289 0.25 watt and MGA-31389 and MGA-31489 0.10 watt Gain Blocks are made possible by Avago's proprietary, 0.25 µm GaAs Enhancement-mode pHEMT semiconductor process.
Avago's newest power amplifier family is optimized for frequency in order to deliver better performance 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, thus the MGA-31x89 series covers all the major cellular bands - GSM, CDMA, and UMTS - plus next generation LTE bands.
The family offers a choice of power levels in each pair of frequency-optimized devices, and these devices are designed with a common package footprint and pin-out and a single PCB design supports multiple frequency bands. This simplifies the PCB layout and overall design for system engineers developing new LTE band infrastructure.
Available in the compact, industry standard SOT-89 package, the new Avago MGA-31x89 0.25 watt and 0.10 watt gain block power amplifiers can also replace existing market solutions as a pin-to-pin, drop-in replacement offering better linearity and power performance.
