Bias Tees

TTE’s bias tees are available for frequencies from 10 MHz to 40 GHz. These passive devices help insert/remove DC current or voltage to/from RF circuits without impacting the RF signal.

Bias Tee Types:

  • High Current – specifically designed to handle up to 7 A DC and frequency up to 6 GHz
  • High Frequency –  two models provide robust performance to either  27.5 or 40 GHz
  • Standard – multiple models address frequencies within the range of 10 MHz to 18 GHz

Key Features:

  • Superior broadband performance
  • Low insertion loss
  • Minimal return loss
  • Desirable VSWR characteristics
  • Extremely flat gain response
  • RoHS-compliant options

*For RoHS compliant, insert “R” in place of asterisk.  Example: BTHCR-4G
TTE designates a component RoHS-compliant by adding “R” (RoHS) within the part number.
These RoHS components meet the ≤0.1% lead requirement.

Notes:

TTE offers its products in the smallest practical sizes available.  SMA connectorized cases (female) are typically utilized for the bias tees.  Please contact TTE to discuss other options.
