RF Limiters

The Teledyne e2v HiRel family of limiters offers solutions for military and aerospace applications.  Operating in frequencies from 2 MHz up to 6 GHz and attenuating RF signals up to 1000W (peak), these limiters can address many limiting requirements in military and orbital applications.

HiRel Expands Family of PIN Diode Limiters for Military Applications

Teledyne e2v HiRel announced two new additions to its family of high-power limiters, the TDLM052402, a quasi-active, 2 kW, L/S/C-band SMT PIN Diode Limiter and the TDLM961122 High Power Limiter Module a quasi-active, 1 kW, ARNS/IFF-band SMT PIN Diode Limiter. Both devices offer “always on” high power CW and peak protection.

Two New Power Limiters for Space  

The first, model TDLM025100, is a 2.5 GHz, 100 W RF power limiter. The second limiter, model TDLM06100, is a 6.0 GHz, 100 W solution. Both are radiation tolerant, monolithic ‘all-in-one’ limiters based on Silicon-on-Insulator technology that are ideal for high reliability aerospace and defense applications.
