3 dB Hybrids, CA series Quadrature Couplers, 90 Power Dividers 200 to 4000 MHz Octave bands to 4 GHz See wireless versions for special low PIM and multi band coverage 100W average Power Rating High Isolation, Low VSWR N Connectors The Microlab 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 380 to 2700 MHz bands to combine two signal sources to a single antenna. This application requires a hybrid with very low passive intermodulation (PIM). Custom versions are available with special bandwidths or alternate connectors on request.
