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 p
ort
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 require
s 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. (9/99)
