GNSS diplexers : Popular manufacturers & their products with key features

gnss diplexer

GNSS diplexer is an RF component which combines or separates signals from multiple GNSS bands such as L1, L2 and L5 within a single antenna system. This enables devices to receive signals from various satellite constellations (e.g. GPS, GLONASS, Galileo, BeiDou) simultaneously. This enhances positioning accuracy and reliability. The RF center frequencies for L1 is 1575.42 MHz, L2 is 1227.60 MHz and for L5 is 1176.45 MHz.

Key Features of GNSS Diplexers

  • As mentioned it facilitates concurrent reception of multiple GNSS bands
  • Available in surface mount packages suitable for space constrained designs.
  • Due to higher isolation, it minimizes interference between bands
  • Due to low insertion loss, it ensures efficient signal transmission
