Single low noise LNA supports consumer, military and industrial applications up to 3.8GHz
OEMs can now use 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 0.25um 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 megahertz 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.
“Skyworks’ newest LNAs are achieving unprecedented performance levels, while enabling a multitude of high performance base station, cellular repeater and remote radio head platforms,” said David Stasey, vice president and general manager of analog solutions at Skyworks. “Leveraging our analog design expertise, IP and scale, Skyworks is delivering highly differentiated solutions and creating competitive advantages for our customers.”
The new LNAs are currently available for both sampling and production.
