Skyworks Unveils Next-generation Ultra Low-noise Amplifiers
Skyworks Solutions Inc., an innovator of high reliability analog and mixed signal semiconductors enabling a broad range of end markets, introduced two next-generation low noise amplifiers (LNA) 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.
“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 to 2.0 GHz) and the SKY67101-396LF (0.7 to 1.0 GHz) are gallium arsenide (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 small, low-cost, 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.
