Anritsu MA2473A Power Sensor, 10MHz to 32GHz

The Anritsu MA2473A is a precision power sensor engineered for accurate measurements across 10 MHz to 32 GHz. It delivers high sensitivity and dynamic range performance across CW, peak power, and multi-carrier signal environments including N-CDMA, intermodulation, and satellite applications. The sensor employs fast diode response, excellent return loss design, and factory calibration data stored in internal EEPROM to minimize mismatch uncertainty and measurement ripple. Rise and fall times of <4 µsec and <10 µsec respectively enable on-pulse measurements over more than 80 dB dynamic range, making it ideal for wireless communications, radar systems, and microwave component characterization.
