MILPITAS, Calif. 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.

The new power limiter modules are packaged in a small 8 mm x 5 mm form factor designed for demanding electronic warfare (EW) and radar applications, using proven hybrid assembly technology. Parts are screened and qualified for high-reliability applications.

Each has an operating temperature range of -65 °C to 125 °C. They boast excellent thermal-management features, with a proprietary design methodology that minimizes thermal resistance from the PIN diode junction-to-base plate (RTHJ-A). The limiter design employs a two-stage detector circuit which enables ultra-fast turn-on of the high-power PIN diodes.
