Broadband Limiting Amplifiers up to 18 GHz Available for Immediate Delivery

Pasternack has expanded its range of broadband limiting amplifiers which are commonly used in electronic warfare, microwave receivers and broadband communications systems. The 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.

These RF amplifiers offer a wide input dynamic range between -61 dBm to +20 dBm, high gain levels of 40 to 80 dB typical 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.

These 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 Celsius. 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 customer's need for additional sensitive, external RF tuning components.

Pasternack's five models of limiting amplifiers include:

  • PE15A6002 - Provides 60 dB of gain and operates from 1 GHz to 2 GHz
  • PE15A6015 - Provides 40 dB of gain and operates from 2 GHz to 4 GHz
  • PE15A6007 - Provides 80 dB of gain and operates from 2 GHz to 6 GHz
  • PE15A6008 - Provides 40 dB of gain and operates from 2 GHz to 8 GHz
  • PE15A6012 - Provides 40 dB of gain and operates from 6 GHz to 18 GHz

Pasternack's broadband limiting amplifiers are in-stock and ready for immediate shipment with no minimum order quantity.
