Ultra low noise figure amplifiers suit 4G applications
OEMs can now leverage a single LNA to address all cellular, ISM and military bands, enabling unconditional stability and simple band specific external matching across a wide voltage range.
The SKY67151-396LF is a high performance gallium arsenide, pseudomorphic high electron mobility transistor LNA with integrated active bias and very low noise figure (as low as 0.25 dB). The advanced 0.25 µm enhancement mode process provides broadband return loss, high gain, very low noise and high amplifier linearity. The internal active bias circuitry provides stable performance over temperature and process variation. The device allows users to externally adjust supply current to optimize linearity and provides best-in-class noise figure.
The new LNA operates over the broad frequency range of 0.7 to 3.8 GHz. Four band-specific external tuning networks with common printed circuit board layouts are available to cover the full 3,000 MHz bandwidth. This device is ideally suited for both macro and micro cellular base stations, repeaters, remote radio heads, tower mounted amplifiers, L&S band military communication, global positioning transceivers and proprietary radio networks.
The LNA is manufactured in a compact 2 x 2 millimeter, 8-pin, dual flat no-lead Skyworks Green package and four band specific evaluation boards are available for customer testing.
