The Marconi IFR Aeroflex 56910/900 is a medium power thermocouple sensor for direct RF power measurement across 10 MHz to 20 GHz. It delivers ±0.5% accuracy in the +10 to +20 dBm range and integrates with industry-standard power meters to support calibration, characterization, and field validation of RF and microwave systems. Compact, rugged, and field-repairable, this sensor handles continuous power to +25 dBm (300 mW) and peak levels to +42 dBm (15 W, 2 µs pulses) without performance degradation.
