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.
