Non-Directional RF Power Sensors
4044 RF Power Sensors are economical and capable of measuring the output power of either analog or digitally modulated radios, at power levels up to 125 watts. The 4044 RF Sensor is accurate to within +/-5% of reading with traceability to NIST. This sensor is a non-directional sensor that is ideal for use at the input to each channel of the transmit combiner where the VSWR is well controlled.
