Quadrifilar

Quarifilar has one input port and four (4) outputs with 0 °, 90 °, 180 °, 270 ° phase difference

output port. Its internal circuit has the same structure as three Hybrid Couplers.

Quadrifilar maintains low insertion loss compared to complex structure, and Q type and M type

There are two models. The Q type is small in size with an internal resistor inserted

And the M type has no internal resistance, so the user must put a resistor outside the product.
