Sirenza Microdevices announced the production release of the SPF-5043Z and SPF-5122Z high performance enhancement mode PHEMT MMIC low noise amplifiers (LNA).

These LNAs offer sub-1 dB noise figure and high linearity in an easy-to-use active-biased gain block configuration. Fully integrated impedance matching circuitry eliminates the need for external matching components and stability-compromising series feedback, and on-chip active bias circuitry helps to eliminate the risk of performance degradation associated with process threshold voltage variation. These new RF MMICs are very compact, easily integrated, high performance LNA solutions that minimize design-related issues typically associated with pHEMT or GaAs-based FET LNAs.

"This level of performance in a cascadable 50 Ohm MMIC makes these LNAs ideal solutions for high dynamic range wireless infrastructure receiver front-ends. The SPF-5 products offer an exceptional combination of excellent noise figure, high linearity, bias flexibility and ease-of-use," said Jeff Gudewicz, Sirenza’s SBU director, standard and catalog products. "With the addition of the SPF-5 series of LNAs to its amplifier portfolio, Sirenza continues to deliver state-of-the-art technology necessary for success in today’s wireless communication systems."
