The Anritsu MA2445D is a high-accuracy diode power sensor engineered for precise CW average power measurements across 10 MHz to 50 GHz. With an 87 dB dynamic range and sensor linearity of 3.5% up to 50 GHz, it delivers reliable measurements from -67 dBm to +20 dBm, making it ideal for RF and microwave applications including amplifier testing. The sensor features a built-in 3 dB attenuator to minimize input VSWR and employs precision RF connectors with hexagon coupling nuts for standard torque wrench attachment. Calibration factors are stored in onboard EEPROM for repeatable operation.
