Marconi IFR Aeroflex 6923 – 10MHz-26.5GHz Power Sensor

The Marconi IFR Aeroflex 6923 is a precision RF power sensor for accurate measurements from 10 MHz to 26.5 GHz. It measures power levels spanning -70 dBm (100 pW) to +44 dBm (25 W) with 0.01% resolution and supplied linearity correction data. The sensor features a field-replaceable RF assembly, low VSWR, high overload capability, and rugged construction suitable for bench and field deployment. Its compact form factor—88.5 mm length, 33.5 mm diameter, 140 g weight—combined with MPC 3.5 mm male 50 Ω connectors makes it portable without sacrificing measurement integrity across demanding RF and microwave applications.
