General Notes:
1. The QHG-2B series includes narrowband devices covering 1 to
1,000 MHz using a special lumped element design to minimize size
and cost. The low profile, surface-mount package which houses these
3 dB Quadrature Hybrids is suited for terrestrial and aerospace
applications alike where hermeticity and inherent package reliability
are essential.
