Anritsu MA2475D Standard Diode Power Sensor (CW), 10 MHz to 50 GHz

Standard CW diode power sensor covering 10 MHz to 50 GHz with a -70 to +20 dBm dynamic range and a V(m) connector.

Frequency Range: 10 MHz - 50 GHz
Video Bandwidth: 100 kHz

Overview

The Anritsu MA2475D is a standard diode power sensor in the MA247xD series. It is designed for use with the ML2430, ML2480 and ML2490 series power meters and covers the frequency range from 10 MHz to 50 GHz through a V(m) connector.

The sensor is intended for high dynamic range, high accuracy CW and TDMA measurements. It has a dynamic range from -70 dBm to +20 dBm. On the MA2475D, the specified sensor linearity applies from -70 dBm to +15 dBm only.

With a rise time of less than 4 µs, the sensor is fast enough to measure power on GSM and similar TDMA systems that use GMSK modulation. Calibration factors are stored in the sensor's EEPROM.

The RF connector is a precision connector with a hexagon coupling nut, so it can be attached with an industry-standard torque wrench.
