Anritsu MA2472B Diode Power Sensor, 10MHz to 18GHz

The Anritsu MA2472B is a diode power sensor engineered for precision RF power measurement from 10 MHz to 18 GHz. It delivers 90 dB dynamic range across a -70 dBm to +20 dBm measurement span, with linearity better than 1.8% throughout the full frequency band. The sensor employs internal EEPROM calibration storage that automatically interpolates corrections as a function of frequency, power, and temperature - eliminating manual recalibration steps.

A 4 µs rise time enables accurate capture of pulsed signals, making it particularly effective for TDMA-modulated systems including GSM.
