General Notes:

1. The QHF-2-G series consists of quadrature backward-wave hybrid couplers which use shielded stripline design techniques to cover

octave bands in the frequency range 54 MHz to 2 GHz.

2. The Filmbrid™ Sandwich Package is sealed under heat and pressure insuring the printed substrates and low-loss dielectric laminates

are permanently bonded to minimize the effects of dirt and moisture and prevent separation when subjected to shock and vibration.

3. The QHF-2-G series is ideally suited for applications requiring high performance, inherent reliability and low cost. Special customized

units are available for special bandwidth and frequency applications.
