KRYTAR has developed a line of broadband coaxial limiters for applications from 0.5 to 18 GHz. The two families of KRYTAR limiters include the Broadband PIN-Schottky Diode Limiters and Broadband PIN-PIN Diode Limiters. These PIN (positive-intrinsic-negative) diode designs exhibit very low insertion loss at a maximum of 2.5 dB and are cylindrical coaxial packages available with SMA female output and SMA male input connectors. KRYTAR diode limiters are broadband passive devices which find uses in receiver and RF component protection in addition to power leveling applications.
