The Anritsu MA2442D 18 GHz High Accuracy Diode Sensor is designed for use with the ML2430, ML2480 and ML2490 series power meters. They are designed for high dynamic range, high accuracy CW and TDMA measurements. With a built-in 3 dB attenuator, the MA2442D minimizes input SWR and is best used where the best measurement accuracy is required over a large dynamic range, as when measuring amplifiers. The MA2442D sensor has a dynamic range of 87 dB compared to the 90 dB dynamic range of MA247xD standard diode sensors. Specifications. Frequency Range: 10 MHz to 18 GHz. Dynamic Range: –67 dBm to +20 dBm. SWR: <1.17; 10 MHz to 50 MHz, <1.17; 50 MHz to 150 MHz, <1.08; 150 MHz to 2 GHz, <1.16; 2 GHz to 12.4 GHz, <1.21; 12.4 GHz to 18 GHz. Rise Time (the time interval necessary for the power sensor to rise from 10% to 90% of the reading when the signal rises instantaneously from zero (no power) to 1 mW (0 dBm) at room temperature): <0.004 ms. Sensor Linearity –67 to +20 dBm: 1.8% <18 GHz. RF Connector Type: N (m). Maximum Input Power: 23 dBm, CW; 30 dBm, 1 µs peak, ±20 Vdc.
