Freescale Semiconductor has introduced a 2W integrated power amplifier (PA) that works with a 5V supply and delivering more than 40dB of gain to cover all frequency bands between 1500MHz and 2700MHz. The MMZ25333B supports any cellular standard operating at this frequency including GSM, 3G, 4G and LTE, added the company.

The MMZ25333B is intended 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 PA based on InGaP GaAs HBT technology and is housed in an industry-standard 4mm QFN package. Production-ready samples of the MMZ25333B are available and the device is planned for full production in April 2014.
