From RF Micro Devices Inc. comes the RF5616 highly integrated 4.9GHz to 5.8GHz (ISM band) 3mm x 3mm power amplifier (PA) designed to significantly reduce customers' total solution size and cost. The RF5616 is targeted for high-performance mobile PC and embedded applications including access points, gateways, DSL routers, wireless high definition interface, and WLAN for wireless video distribution networks.

The RF5616 features a fully matched product design (I/O) and integrated low pass filtering to require only two external bypass components. The RF5616 includes an integrated three-stage PA that provides high gainan first for 5GHz band front-ends, as well as wide range of voltage supply levels (3V to 5V), enabling high linear output power of 18dBm to 21dBm.

The amplifier also features an interstage power detector, reducing sensitivity to voltage supply, temperature extremes and VSWR while improving accuracy of the closed loop power control. Additionally, a variable linearity mode control enables two modes of operationsa maximum output power and linearity mode, or a more efficient lower output power mode, with a single control pin. Finally, integrated harmonic attenuation eliminates the need for additional filtering, therefore optimizing the efficiency and maximizing output power at the transmit port.

A direct-to-battery connection eliminates the need for additional DC circuitry, while integrated input and output matching eliminates the need for additional RF matching. The RF5616 is fully tested and available in an industry-leading 3mm x 3mm leadless QFN package with backside ground.

The RF5616 is available immediately and volume pricing begins at $0.92.
