Surface Mount Power Limiters

Surface Mount Power Limiters

This series of surface mount limiters was developed to offer higher power handling than our conventional limiters in a small compact design. Covering the band from 20 - 6000MHz these devices can limit input power levels of 10W CW over the operating temperature range of -55C to +85C. Peak power handling is rated to 1kW with a 1us pulse width and a 0.1% duty cycle. Typical leakage levels are less than 12.5dBm (measured at 1W input). These units are available in both drop-in and surface mount packages. Coaxial configurations are available upon request.

Features:
  • Low Insertion Loss
  • Low Leakage Power Circuit Protection
  • High CW Power Handling
  • Hermetically Sealed Modules
