LDCBS1X4 Passive GPS Splitter

LDCBS1X4 Passive GPS Splitter


  • Precise Amplitude Balance
    - Less than 1 dB variation between ports.
  • Flat Group Delay
    - Less than 1ns variation between L1 and L2.
  • Low Insertion Loss
    - -7.5dB loss is typical across all operating frequencies.
  • Wide Accepted Frequency Range
    - Accepts signals from the entire L-Band, covering all major GNSS constellations.
  • Efficiently Blocked Ports
    - Uses 200Ω resistors to prevent antenna alarm faults from connected devices.
  • Matched Phase Balance
    - Less than 1° of variation between ports.


This Loaded DC Blocked Splitter 1X4 (LDCBS1X4) is a passive one input, four output RF splitter that splits signals from 1.1 GHz to 1.7 GHz. This equipment is designed to split signals within the L-band to provide multiple devices with the signal from a single antenna. In the standard configuration, the J1 port will pass DC voltage from a connected device and pass this power to the antenna or other devices upline from the splitter. The other ports (J2-J4 are DC blocked and loaded with 200Ω resistors to simulate antenna current draw which prevents antenna alarm faults. Custom gain configuration, DC configuration, and connector configuration are available upon request.

Use Cases

• Splitting a roof antenna signal between 4 GPS/GLONASS/GNSS receivers.
• Splitting a WAAS antenna between WASS receiver, ADS-B, and 2 other devices.
• Splitting a roof antenna signal to 4 passive antennas to re-radiate from 4 antennas.
• Usable as a smaller part in larger signal distribution networks.
