Richardson RFPD introduces power limiter for UHF-band applications

Distributor, Richardson RFPD, now offers the 360W CW power limiter for UHF-band applications from Macom Technology.

It provides full design support capabilities for the MADL-011012 power limiter. The device is a led-free, surface mount, high-power limiter, with an operating frequency range from 0.3 to 1.0GHz. It integrates the equivalent of 20pin, Schottky, limiter diodes, capacitors, inductors and resistors in a compact ceramic package, measuring 10.1 x 6.2 x 3.2 mm3.

The limiter functions without DC bias and features insertion loss of 0.2dB and return loss of 25dB at 400 to 500MHz. It provides 360W power handling at 25 degree C and flat leakage power of +20dBm.

The power limiter can be used for high peak and CW power receiver-protector microwave circuit applications, including aerospace and defence, handheld communications and radar.

Additional features are 55.6dBm CW power handling at +25 degree C and 54dBm CW power handling at +85 degree C.
