Bird - The RF Experts

25 MHz to 1 GHz, 0.5 to 500W
RF Power Sensor

The 7020-1-030301 RF Power Sensor is an economical, plug and play solution to your power measurement needs. The 7020 determines and reports Forward and Reflected True Average Power and VSWR over a wide frequency range of 25 MHz to 1.0 GHz. It also never requires field calibration, only requires factory calibration once per year and is traceable to National Institute of Standards and Technology (NIST).
