The Marconi IFR Aeroflex 56914/001 is a semiconductor thermocouple power sensor engineered for precision RF power measurements spanning 10 MHz to 40 GHz. Operating across a −30 dBm to +20 dBm measurement range, this medium-power sensor delivers ±0.5% accuracy at 25 °C and 100 mW with 0.01% resolution. The sensor accepts a male MPC 2.92 mm connector (50 Ω) and withstands continuous RF input up to +25 dBm (300 mW), plus peak overload to +42 dBm (15 W) for 2 ms pulses. A field-replaceable RF sensing assembly minimizes service downtime.
