Avago releases family of four high performance SOT-89 power amplifier gain blocks for cellular infrastructure

SAN JOSE, USA & SINGAPORE: Avago Technologies has 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.

The MGA-31189, MGA-31289, MGA-31389, and MGA-31489 are available in a RoHS compliant, halogen-free, SOT-89 plastic package with dimensions of 4.5x4.1x1.5mm.

Avago’s 0.25 W MGA-31189 and MGA-31289 high gain power amplifiers are priced at $1.98 each in 10,000 piece quantities. Avago’s 0.10 W MGA-31389 and MGA-31489 high gain power amplifiers are priced at $1.52 each in 10,000 piece quantities.

Samples, a demonstration board and production quantities are available now through Avago’s direct sales channel and worldwide distribution partners.
