General Notes:
1. The QHZ-2A series of
CaseFree
3 dB
Quadrature Hybrids has been designed for size
and process compatibility with MMIC and similar
devices. This series has narrow band
applications and a profile height of less than
0.130" allowing mounting with similar miniature
components within a low profile hermetic
housing.
2. High performance remains uncompromised by
the units’ miniature characteristics and very low
weight. Additional models are being designed
and will be available as catalog standard units.
3. All units can be supplied screened for
compliance with specifications you designate for
aerospace applications requiring the highest
available reliability.
