General Notes:
1. The QHF-2A series of Quadrature Hybrids covers 1 MHz to 1000 MHz using
special lumped element circuits to minimize parts count and size for applications
requiring an ultra-miniature package. High performance is achieved in the
0.385" by 0.5" flatpack housing that is ideally suited to aerospace applications
where inherent package reliability and hermeticity are essential.
