Sirenza Microdevices Launches High Linearity Amplifier IC with Self-Bias Operation

(Product News, 14 Apr 2007)

Sirenza Microdevices has announced the production release of the SXE-1089Z, a new high linearity cascadable pHEMT amplifier IC. Its patented self-bias Darlington topology, coupled with a robust e-mode pHEMT process, allows the SXE-1089Z to deliver excellent performance normally found in discrete transistor or power amplifier topologies. The SXE-1089Z also offers "ease-of-use" for amplifiers in this power range with its fully integrated matching over 50MHz to 3GHz.

"The SXE-1089Z is ideal for PA driver applications for TD-SCDMA and WCDMA applications requiring high linearity," stated Jeff Gudewicz, Sirenza’s SBU director, standard and catalog products. "The patented self-bias topology allows designers to easily integrate into single-supply, 5V applications without the need for any external dropping resistors."

Key performance characteristics of this advanced IC product include backed-off ACPR performance and excellent bias stability over temperature. Operating at 5V/128mA the SXE-1089Z delivers 13.2dBm IS95 channel power (880MHz) at -65dBc ACPR. Under WCDMA conditions at 2140MHz the SXE-1089Z delivers 9.5dBm at -65dBc ACPR. P1dB is 22.9dBm with 38.5dBm OIP3 at 1960MHz.
