Pasternack Enterprises has released a new family of low-noise amplifiers (LNA) capable of high gain and broadband performance between 9 KHz and 18 GHz. A total of 14 new low-noise amplifiers provide a choice of noise figures, gain levels, frequency ranges and power outputs depending on the intended use. Options include noise figures between 0.8 dB to 3 dB, gain levels from 25 dB to 50 dB, gain flatness from ±0.75 dB to ±1.25 dB and power output levels (P1dB or Psat) between 10 dBm and 18 dBm. The performance of these low noise amplifiers is achieved using a hybrid microwave integrated circuit design and advanced GaAs PHEMT technology.
The amplifiers are connectorized SMA modules that are unconditionally stable and include built-in voltage regulation, bias sequencing and reverse bias protection for added reliability. Depending on the intended application of these RF amplifiers, both hermetically sealed and non-hermetically sealed versions are available. The low noise amplifiers are fully matched internally for input and output at 50 ohm, which eliminates the customers need for any sensitive external RF tuning components. www.pasternack.com
