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.
