The quadrifilar is a 4-phase antenna feeder with world-class RF performance for Helix antenna design. It contains 3 couplers with or without termination included.
It can be used in L-Band mainly for GNSS and satellite applications and it can also be used for RFID transmitters in the ISM 2400 band.
The quadrifilar are designed with low insertions loss and high isolation between ports and with an accurate phase and amplitude balance.
Evaluations boards are available for concept and performance testing.
