Pasternack low-noise amplifiers

Pasternack Enterprises has released a family of low-noise amplifiers which are widely used across the spectrum of military and commercial applications. A total of 14 amplifiers is offered, providing a choice of noise figures, gain levels, frequency ranges and power outputs depending on the intended use.

The series exhibits good broadband performance from 9 kHz to 18 GHz, noise figures between 0.8 and 3 dB, gain levels from 25 to 50 dB, gain flatness from ±0.75 to ±1.25 dB and power output levels between 10 and 18 dBm. The performance of the amplifiers is achieved using a hybrid microwave integrated circuit design and advanced GaAs PHEMT technology.

The amplifiers are connectorised SMA modules that are unconditionally stable and include built-in voltage regulation, bias sequencing and reverse bias protection. Depending on the intended application of the amplifiers, both hermetically sealed and non-hermetically sealed versions are available. The amplifiers are fully matched internally for input and output at 50 Ω, which eliminates the need for any sensitive external RF tuning components.
