Pasternack debuts GaN-based input-protected LNAs

Pasternack Inc of Irvine, CA, USA (an Infinite Electronics brand that makes both passive and active RF, microwave and millimeter-wave products) has launched a new series of low-noise amplifiers (LNAs) suitable for use in electronic warfare (EW), electronic counter-measures (ECM), microwave radio, VSAT, SATCOM, radar, space systems, R&D, prototype/proof-of-concept, and test & measurement applications.

Pasternack’s new series of input-protected LNAs feature gallium nitride (GaN) technology, which provides robust input power protection. GaN ensures state-of-the-art performance with excellent power-to volume ratio that is suitable for broadband high-power applications. The amplifiers offer excellent thermal properties and a significantly higher breakdown voltage that results in tolerating higher RF input power signal levels while maintaining excellent low noise-figure performance. This is done without the need for an input protective limiter circuit that is required for other semiconductor technologies and could contribute to higher noise figure levels.

The new input-protected low-noise amplifiers cover desirable microwave and mm-wave frequency bands that complement Pasternack’s existing portfolio of input-protected LNAs that cover lower RF frequencies. Features and options include broadband frequencies ranging from 1GHz to 23GHz, high gain up to 46dB typical, noise figures as low as 1.5dB typical, and high RF input power handling up to 10W CW. Additionally, the LNAs have a rugged, mil-grade compact coaxial design and SMA connectors.

“Our new, innovative line of input-protected low-noise amplifiers offer the desirable benefit of rugged GaN semiconductor technology to withstand higher RF input power handling without incurring damage,” says product line manager Tim Galla. “RF designers will find these industry-leading GaN low-noise amplifiers extremely useful in receive chains that may be sensitive to higher RF input signal conditions,” he reckons.

The new input-protected LNAs are in-stock and available for immediate shipping with no minimum order quantity (MOQ) required.
