Anritsu MA2474D – Standard Diode Sensor

The Anritsu MA2474D is a standard diode sensor for precision RF and microwave power measurements from 10 MHz to 40 GHz. It delivers high accuracy across continuous wave and TDMA applications, with dynamic range spanning -70 dBm to +20 dBm and sensor linearity better than 1.8% below 18 GHz. The sensor integrates directly with Anritsu ML2430, ML2480, and ML2490 series power meters, offering engineers a fast, accurate measurement tool with rise time under 4 µs - ideal for GSM and modulated signal analysis.

Its 50 ohm input impedance, K-type male connector, and EEPROM-stored calibration factors ensure reliable operation in demanding test environments.
