RF Power Transistor Matching, Testing & Sorting

Due to the stringent system specifications in today’s RF systems, RF Power device performance is critical. In any design that uses multiple RF Power transistors in parallel, using matched devices is the single most important factor in ensuring the design is optimized. There are also cost advantages to receiving product as matched pairs.  

Richardson RFPD provides parametric matching (both DC & RF) for all of our RF Power transistors.

Testing & Sorting (Binning) of DC Parameters for Bipolar and FET Devices

  • Bipolar -V(BR)CBO V(BR)CES V(BR)CEO V(BR)EBO ICBO ICES IEBO and hFE
  • FET - V(BR)DSS IDSS IGSS VGS(TH) VDS(ON) and gfs

Matching Devices: Devices should be matched if being paralleled or used in a push-pull circuit.

  • hFE - DC current gain (for bipolar transistors)
  • gfs - Forward Transconductance (for FETs)
  • Gate Threshold Voltage (for FETs)
  • Power Gain (Requires customer's test fixture)
  • Other parameters that customer may require

Selection of Transistors to Specific Parameter Ranges

  • hFE - DC current gain (for bipolar transistors)
  • gfs - Forward Transconductance (for FETs)
  • Gate Threshold Voltage (for FETs)
  • Other parameters that a customer may require

Selection of Low Leakage Current Devices

  • Selection of devices with low reversed biased junction currents

RF Testing(Requires customer's test fixture)

  • IMD - Intermodulation Distortion
  • IP3 - Third Order Intercept
  • Power output
  • Gain
  • Other parameters that customer may require

Provide Hard Copy of Test Data Modifications

  • Branding to customer specifications
  • Cutting/Milling of leads, flanges and studs
  • Special lead trimming and forming
  • Gold-plating of flanges and studs
  • Enlarge flange holes

Custom Branding/Marking

  • Brand device with customer's part number
  • Color dots or letter codes for sorting and selection
  • Alphanumeric codes for date, lot, etc.
