Dimensions in inches over millimeters. 27Mar96 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.
