Pasternack releases amplifiers for commercial and military radar

April 22, 2014. Pasternack Enterprises Inc., a manufacturer and supplier of RF, microwave, and millimeter-wave products, has released a new portfolio of L- and S-band high-gain amplifiers covering 1.2 to 1.4 GHz and 3.1 to 3.5 GHz. The amplifiers specifically target commercial and military radar applications as well as observation satellites and communications systems.

Pasternack’s new high gain amplifier modules are packaged in hermetically-sealed metal enclosures and exhibit high gain, gain flatness, high output power, and low noise. These RF amplifiers utilize a hybrid microwave integrated circuit design and advanced GaAs pHEMT technology to produce an unconditionally stable module. They are also designed with built-in voltage regulation, bias sequencing, and reverse bias protection for added reliability, and over-voltage protection is installed externally for easy repair.

A total of six new L- and S-band high-gain amplifiers are offered in this latest release. Two of those products are low-noise amplifiers (LNA), which demonstrate noise-figure performance of 1.1 dB to 1.5 dB at high gain levels of 40 dB typical while also exhibiting excellent gain flatness. Also offered are 10-W and 20-W high-power amplifiers that have exceptional gain performance of 40 to 47 dB with 1.0-dB to 1.5-dB gain flatness. Pasternack is also releasing an L-band driver amplifier that displays solid gain performance of 47 dB while delivering competitive gain flatness of 1.5 dB.

“The introduction of our new GaAs-based high-gain amplifiers provides our customers a comprehensive portfolio of amplifier solutions for use in the L and S frequency bands for commercial and military radar applications,” said Michael Rachlin, active RF/microwave products manager at Pasternack. “The rapid growth of our active component product lines illustrates Pasternack’s new strategy to become a leading supplier of active products in the availability market.”
