The Marconi IFR Aeroflex 6914 is a thermocouple power sensor engineered for accurate RF and microwave power measurements from 10 MHz to 40 GHz. It delivers ±0.5% accuracy at 25 °C and 100 mW, with 0.01% resolution across a -30 dBm to +20 dBm operating range. The sensor accommodates peak RF input power of +42 dBm (15 W) for 2 ms bursts, making it suitable for both continuous and pulsed measurement scenarios.
Designed for laboratory and field deployment, the 6914 features a field-replaceable RF assembly, high overload capability, and rugged construction that minimizes maintenance downtime. Its semiconductor thermocouple sensing element connects via a precision MPC 2.92 mm male connector (50 Ω) and integrates with Aeroflex power meters and microwave test sets. The compact form factor—88.5 mm length, 33.5 mm diameter, 140 g weight—enables portable operation without sacrificing measurement fidelity.
