Broomfield, Colo.—Sirenza Microdevices released two additions to its product line for Mobile WiMAX (802.16 e) and WiFi (802.11 b/g/n) applications.

The SZM2166Z and SZM3166Z are high linearity power amplifiers increasing the linear power for WiMAX and WiFi Terminals to more than +27 dBm, enabling increased range and higher data throughput in consumer terminals and access points.

Produced using InGaP HBT technology, the SZM2166Z operates over the full 2.3- to 2.7-GHz frequency range with 36-dB of gain and provides more than +27-dBm of linear power @ 2.5% EVM. The SZM3166Z operates over the 3.3- to 3.8-GHz frequency band with 35-dB gain and also provides +27-dBm of linear power @ 2.5% EVM.

Both products operate from a single positive supply and feature an adjustable on chip active bias circuit providing the designer with the flexibility to optimize performance for the specific application. Both products also feature power up / power down control to save power during receive modes and an on chip power detector.

The devices are housed in a low cost surface mount 6x6 QFN package, have an ESD rating of class 1C (1KV HBM) in accordance with Sirenza's 3R program for reliable, rugged and robust performance.

The SZM2166Z and SZM3166Z are available for immediate shipment in a RoHS compliant, lead-free package.

Datasheets: SZM2166Z and SZM3166Z.
