Freescale Semiconductor claims to offer the first 2-W integrated power amplifier operating with a 5-V supply and delivering more than 40 dB of gain to cover all frequency bands between 1500 MHz and 2700 MHz. The MMZ25333B supports any cellular standard operating at this frequency including GSM, 3G, 4G and LTE.

The high gain MMZ25333B is suitable for driver and pre-driver applications in macrocell base stations, and final-stage applications in small cells. The high performance and integration of the PA help customers reduce part counts, streamline supply chains and optimize costs. Further, since the device can be used across multiple platforms and frequency bands, it can be reused from project to project, simplifying supply chain inventory.

The MMZ25333B is a multi-stage power amplifier based on InGaP GaAs HBT technology and is housed in an industry-standard 4 mm QFN package.

Production-ready samples of the MMZ25333B are available now and the device is planned for full production in April 2014.
