Broadband limiting amplifier line from Pasternack adds new models

June 15, 2017 // By Jean-Pierre Joosting
Pasternack has expanded its offering of broadband limiting amplifiers which are commonly used in electronic warfare, microwave receivers and broadband communications systems.

These coaxial broadband limiting amplifiers cover a wide frequency range from 1 GHz to 18 GHz and are used to protect sensitive microwave receivers by "limiting" excessive input power which could potentially create unwanted distortion or even damage the receiver.

Pasternack's RF amplifiers offer a wide input dynamic range between -61 dBm to +20 dBm, high gain levels of 40 to 80 dB typical gain while exhibiting excellent gain flatness performance of ±1 dB depending on the specific model. Additionally, these limiting amplifiers accept a wide range of input power levels, while responding with a limited range of output power between 15 and 19 dBm with a saturated power output deviation of ±0.5 dB over the frequency range, independent of the input.

The wideband limiting amplifiers are housed in hermetically-sealed packages and are designed to withstand harsh environments with operating temperatures ranging from -30 to +70 degrees C. Over-voltage protection is installed externally for easy repair and the amplifiers are fully matched internally for 50 Ohm input and output, which eliminates the customers need for any additional sensitive external RF tuning components.
