10-15 MHz, 3 W to 10 kW

4027A10M, RF Power Sensor is designed for use in semiconductor processing and other precision process applications. At the calibrated frequency and power level, these sensors are capable of 1% accuracy. Intended for use with Bird 4421A Series Precision Multifunction Power Meters, these sensors provide a threefold improvement in long term unit to unit accuracy.


  • Poor production yields - 1% accuracy at specified frequencies and power levels
  • Lack of confidence in measurements - Calibration traceable to NIST
  • Complex tools requiring calibration each time
    • Plug and Play with 4421A Meter
    • Unit does not need to be field calibrated before use
    • Calibrate only once every six months
  • Harmonic content interfering with measurements
  • Wide range of applications requiring various input and output connectors - Dozens of connector options available


  • Frequency Range: 10-15 MHz
  • Power Range: 3 W to 10 kW
  • Accuracy: ±1% at calibration frequencies and power levels
    ±2 % at other frequency and power levels
    Add 2% to uncertainty outside 25 ± 10 C
  • Calibration Power Level: 1000W units: 700 watts
    10kW units: 1700 watts
  • Uniformity: 2 % maximum unit to unit, at calibration frequency and power levels
  • Speed: 2 readings per second
  • Maximum Power: 10 kW units - 12 kW (max)
    1 kW units - 1.2 kW (max)
  • Harmonic Content: -50 dBc (max)
  • VSWR Range: 1.0-2.0
  • Directivity: 28 dB
  • Insertion Loss: <0.05 dB
  • External DC: 12 VDC, supplied from 4421A Multifunction Power Meter
  • Connectors: Input and Output Connectors MUST be ordered separately at additional cost
  • Calibration Cycle: 6 month. Performance before and performance after data to be supplied for units
