General Notes:
1. The QHM-2M and QHM-3M series of
quadrature hybrid couplers covers 500 MHz
to 12.4 GHz in octave and multi-octave
bands, respectively.
2. These units have been designed using
miniature stripline construction to achieve
high isolation and low VSWR. They may be
used in a wide variety of applications
requiring -3 dB power division either
in-phase or in phase quadrature (or both).
Such signals are often required in mixers,
modulators and phase shifters among
others.
NOTES:
1. Tolerance on 3 place decimals
±.020(.51)
except as noted.
2. Dimensions in inches over millimeters.
3. Weights are nominal on all outlines.
