Pasternack Enterprises Inc., an industry leading manufacturer and supplier of RF, microwave and millimeter wave products, unveils new wide dynamic range broadband limiting amplifiers commonly used in electronic warfare, microwave receivers and broadband communications systems.

 Pasternack’s new coaxial limiting amplifiers cover a wide frequency range between 1 to 18 GHz.  These broadband limiting amplifiers are used to protect sensitive microwave receivers by “limiting” excessive input power which could potentially create unwanted distortion or even damage the receiver. This new portfolio of limiting amplifiers from Pasternack accept a wide range of input power levels, while responding with a limited range of output powers between 15 and 19 dBm with a saturated power output deviation of ±0.5 dB over the frequency range, independent of the input. These RF amplifiers demonstrate 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.

 The new 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. The connectorized SMA limiting amplifiers are unconditionally stable and include built-in voltage regulation, bias sequencing, and reverse bias protection for added reliability. 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.

 “Our new offering of broadband limiting amplifiers helps us further answer our customers’ need for a wide variety of off-the-shelf amplifier products where extended lead times are not an option”, says Michael Rachlin, Active RF/microwave Products Manager at Pasternack. “A key element of Pasternack’s new active component strategy is to offer existing and new customers a broad range of amplifier solutions available for the immediate shipment from stock.”

 The new broadband limiting amplifiers from Pasternack are in stock and available to ship now. You can view the entire line of limiting amplifiers by visiting http://www.pasternack.com/pages/Featured_Products/broadband-limiting-amplifiers.htm. Pasternack can be contacted at +1-949-261-1920.
