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.

 What's New?

Two New Power Limiters  

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. Both offer alternatives to the traditional industry alternative of discrete GaAs PIN diode circuits with multiple external components.

New Pin Diode Limiter for Military Apps

Teledyne e2v HiRel has introduced its first high power limiter for military applications, the TDLM202402 PIN Diode Limiter. It is a quasi-active, S-band, SMT, PIN Diode Limiter that offers “always on” high power CW and peak protection. We support SCDs (Source Controlled Drawings), and the devices are tested and shipped from our certified facility in Milpitas, California, one of the industry’s most trusted production locations. The TDLM202402 is designed for optimal small signal insertion loss, permitting an extremely low receiver noise figure while simultaneously offering excellent large input signal.
