Description

The Bias Tee 1X1 (BT1X1) is a one input, one output GNSS bias-tee. This equipment is designed to inject DC voltage into a coaxial cable with minimum RF insertion loss. The BT1X1 is compatible with all L-band and S-band GNSS signals, including GPS, Galileo, GLONASS, BeiDou, and IRNSS. The BT1X1 provides a stable voltage supply and features internal transient suppression technology designed to pass DO-160G Lightning Induced Transient testing on the DC input port. In the default configuration, the J1 RF output is DC blocked while the requested DC voltage is provided to the Antenna port. The BT1X1 is powered by an attached AC transformer or a MIL-DTL-5015 10SL two-pin DC power port.

Use Cases

• Powering antennas, inline amplifiers, splitters, or other GNSS equipment.
• Providing compatibility for equipment with different operating voltages.
  • Using a BT1X1-N/12/110, a 12 VDC antenna can be used with a 5 VDC receiver.
  • Protecting expensive receivers by blocking the DC path from the antenna.
