Datasheet

Overview

The Anritsu MA24004A is a thermal power sensor in the MA2400xA series. It covers 10 MHz to 40 GHz and is designed for use with the ML2430, ML2480 and ML2490 series power meters. The series provides power measurement over 50 dB of dynamic range.

Thermal sensors use Seebeck elements, in which the combined effect of a thermal gradient and charge migration between dissimilar metals gives a true reading of the average power of any incident waveform. This true-RMS detection allows average power measurements of any signal type, independent of modulation or access scheme.

The sensor has a built-in EEPROM that stores calibration factor and linearity correction data. The MA24004A uses a precision K(m) RF connector with a hexagon coupling nut for attachment with an industry standard torque wrench.
