General Notes:
1. The QHZ-23B series of CaseFree 3 dB
Quadrature Hybrids has been designed for size
and process compatibility with MMIC and similar
devices. The series presents a unit profile height
of less than 0.130" allowing mounting alongside
other miniature components within a low profile
hermetic housing.
2. High performance and octave bandwidth
remains uncompromised by the units’ miniature
characteristics and very low weight.
3. All units can be supplied screened for
compliance with specifications you designate for
aerospace applications requiring the highest
available reliability.
NOTES: 1. Tolerance on 3 place decimals ±.010(.25) except as noted.
2. Dimensions in inches over millimeters.
