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. 20Feb96 |
