RF Micro Devices has expanded its wireless infrastructure product portfolio with the introduction of the SPA-1426Z and SPA-1526Z power amplifiers. The devices are one-watt and two-watt, respectively, Indium Gallium Phosphide (InGaP) power amplifiers that address base-station applications across all cellular standards and frequencies. The amplifiers exhibit high linearity performance, which is particularly critical to WCDMA high power amplifier (HPA) applications. Housed in a proprietary SOF-26 package, the devices deliver low thermal resistance and low power dissipation while providing RoHS and WEEE compliance. They feature on-chip active bias circuitry and bias control pins, in addition to an input power detector and rugged class 1C ESD rating (greater than 1 KV human body model).
