MICROLAB/FXR 3 dB Hybrids Quadrature Couplers, 90 Power Dividers 200 to 4000 MHz CA series Octave bands to 4 GHz See CA wireless for special low PIM wireless band versions 100W average Power Rating High Isolation, Low VSWR N Connectors The Microlab/FXR CA series of 3 dB Hybrids are reciprocal 4 port networks also known as Hybrid Combiners, 90 Power Dividers or Quadrature Couplers. Each is designed using stripline construction to achieve high isolation and low VSWR. Common applications includes interfacing drivers with parallel power amplifiers where the reflections due to common load mismatches are combined at the isolated port and cancel at the input providing excellent system match. Wireless versions are designed for use in hybrid combiner applications in the Cellular and PCS bands to combine two signal sources to a single antenna. This application requires a hybrid with very low passive intermodulation (PIM). Units designed for low PIM are described on CA wireless. Custom versions are available with special bandwidths or alternate connectors on request.
