PAs offer final stage gain for picocell/femtocell apps

The MGA43428/43528/43628 power amplifier family provide final stage gain for Picocell and Enterprise Femtocell systems, offering 34 to 40 dB of gain and power-added efficiency ranging from a high of 15% to 13.8%. The power amplifiers are implemented as a three-stage design and display performance of excellent linearity of 50 dBc adjacent-channel leakage ratio at 27.3 dBm output power when biased with a 5-V supply.

Each targeted at a different frequency band — 3GPP bands 5 (MGA43428), 2/25 (MGA43528), and 1 (MGA43628). All are fabricated using 0.25-μm GaAs Enhancement mode pHEMT process and also include a detector block integrated on the chip. The parts are packaged in a 5 x 5 x 1 mm 28-contact QFN package that has a footprint 50% smaller than comparable devices.(Contact company for pricing samples now)
