E-pHEMT Balanced Amplifiers
Avago Technologies introduces a pair of very low-noise, high-linearity, high-gain balanced amplifier modules that operate in the 1.8 to 2.2 GHz frequency range. The modules are housed in a package measuring 5.0 × 6.0 × 1.1 mm to simplify system design and minimize the number of external components. Each amplifier module consists of two branches. Each branch consists of one low-noise transistor cascaded with a high-linearity driver transistor to achieve its combination of noise figure, gain and linearity. Their desirable noise performance is a result of the company’s proprietary 0.5 GaAs EpHEMT process.
