The Anritsu MA2442D is a high-accuracy diode sensor for precision power measurement across 10 MHz to 18 GHz. It delivers an 87 dB dynamic range from −67 dBm to +20 dBm in CW mode, with extended measurement capabilities in profile and pulse/modulation modes when paired with compatible Anritsu power meters. The sensor incorporates a 3 dB attenuator to minimize input VSWR, achieving performance as low as <1.08 across 150 MHz to 2 GHz and maintaining linearity within 1.8% to 18 GHz. Rise time of <0.004 ms supports accurate TDMA and modulated signal characterization.
