Anritsu MA2444D Series – High Accuracy Diodes Sensors (CW)

The Anritsu MA2444D Series High Accuracy Diode Sensors deliver precise CW and TDMA power measurements across 10 MHz to 40 GHz. Built-in 3 dB attenuation minimizes input VSWR, critical for high-gain amplifier characterization. Calibration factors stored in internal EEPROM enable automatic power meter correction. Fast rise time and wide dynamic range support demanding RF and microwave test environments.
