Microwave signal power limiter for radar, has circuit detector and polarization entry to polarize limitations stage diodes using current with power equal to applied microwave signal and external polarization current, respectively
Microwave signal power limiter for radar, has circuit detector and polarization entry to polarize limitations stage diodes using current with power equal to applied microwave signal and external polarization current, respectively
The limiter has a principal line (20) with an entry (21) to receive a microwave signal. A circuit detector (30) generates at its exit (32) a current equaling to power of the signal applied to its entry (31). The detector polarizes diodes of a limitation stage (23) with the generated current. A polarization entry (38) receives an external polarization current to polarize the diodes with the polarization current.
