General Notes:
1. The QHG-22B series covers 1 to 300 MHz in 30% bandwidth
units using a special lumped element design to minimize size
and cost. The low 0.175" profile surface-mount package which
houses these 3 dB Quadrature Hybrids is ideally suited to
terrestrial and aerospace applications alike where hermeticity
and inherent package reliability are essential.
