3 dB Hybrids, CA series
Quadrature Couplers, 90°Power Dividers
200 to 4000 MHz
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 paral-
lel 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 anten-
na. This application requires a hybrid with very low passive inter-
modulation (PIM).
Custom versions are available with special bandwidths or
alternate connectors on request. (03/10)
