Pasternack, an Infinite Electronics brand, has released a new line of input-protected low noise amplifiers (LNA) — with no damage up to +30 dBm CW input power. The family of LNAs comprises 12 models covering frequency bands from 10 MHz to 3.5 GHz, with typical noise figure of 0.8 to 1.6 dB, 25 to 40 dB small-signal gain and low VSWR, from 1.3 to 1.5:1.

The LNAs are well-suited for radar, EW, military radios, wireless, satcom and test instrumentation.

This performance is achieved using hybrid MIC designs that incorporate PIN diode limiters with enhancement mode GaAs PHEMT active devices. The LNA modules have SMA connectors, DC blocking capacitors on the RF ports and built-in voltage regulation and are typically biased with +12 V. The 50 Ω LNAs are unconditionally stable and operate from −40°C to +85°C.

“The robust performance of these LNAs is desirable in maintaining receiver sensitivity over a wide range of RF input signal levels for applications that may involve radar systems, test instrumentation and wireless and satcom. All models are in stock and available for urgent demands with no minimum order quantity required,” — Tim Galla, product manager
