Anritsu MA72A 14 GHz Power Sensor

The Anritsu MA72A is a 14 GHz power sensor engineered for precise RF power measurement across microwave frequencies. When connected to compatible Anritsu power meters such as the ML83A, it delivers accurate power detection from 10 MHz to 14 GHz. The sensor measures power levels from -60 dBm to +20 dBm (1 nW to 10 mW) with calibration accuracy of ±0.15 dB from 10 MHz to 12.4 GHz and ±0.23 dB from 12.4 GHz to 14.0 GHz.

Its compact form factor - 43 H × 53 W × 88 D mm, weighing 300 g - enables portable deployment in laboratory and production environments.
