Anritsu MA2469A Fast Diode Sensor, 10MHz to 18GHz

The Anritsu MA2469A is a fast diode sensor for broadband RF power measurement from 10 MHz to 18 GHz. It delivers high-speed detection with low SWR performance, enabling rapid and repeatable measurements in automated test environments. The sensor captures fast transients with a 0.6 µs rise time, measuring average power, peak power, and crest factor on modulated signals including N-CDMA.

It connects via N-type male connector to Anritsu ML2400 series power meters for integrated RF power characterization.
