Skyworks introduces next-generation LNAs for multiple cellular infrastructure receiver applications

At this week’s IEEE MTT-S International Microwave Symposium (IMS 2010) in Anaheim, CA, USA (25-27 May), Skyworks Solutions Inc of Woburn, MA, USA, which makes linear products, power amplifiers, front-end modules and radio solutions for handset and infrastructure equipment, has introduced two next-generation low noise amplifiers (LNAs) for multiple cellular infrastructure receiver applications, including GSM, CDMA, WCDMA and LTE base stations and repeaters.

These new monolithic microwave integrated circuit (MMIC) amplifiers allow infrastructure providers to meet a wide range of demanding performance requirements with a single device that minimizes system noise figure, improves receiver sensitivity and delivers unconditional stability, says the firm.

"Skyworks is pleased to be expanding our infrastructure product portfolio particularly as estimates for mobile data traffic are expected to double every year through 2014," said David Stasey, vice president of analog components at Skyworks. "These solutions are just one of several devices that help reduce the size and complexity of networking equipment while enabling greater reliability, capacity and efficiency."

The SKY67100-396LF (1.7-2.0 GHz) and the SKY67101-396LF (0.7-1.0 GHz) are GaAs enhancement mode pseudomorphic high electron mobility transistor (pHEMT) LNAs designed for low noise figure down to 0.49 dB while providing unconditional stability and high-linearity performance up to OIP3 of 34 dBm. The addition of an internal active bias circuitry provides stable performance over temperature. These new LNAs are available in a industry-standard 2 x 2 x 0.75 millimeter (mm), 8 pin, dual flat no-lead (DFN) package and are layout compatible with each using a reduced-component matching network.

Skyworks’ SKY67100-396LF and SKY67101-396LF are available now.
