General Notes:
1. The QHF-22A series covers 5 to 300 MHz using a special lumped element design to minimize package size and cost. This series features
a low 0.15" profile package suitable for applications where an ultra-miniature package is essential. The 0.385" by 0.5" flatpack which houses
these 3 dB Quadrature Hybrids is suited to both terrestrial and aerospace applications where inherent package reliability and hermeticity are
essential.
