General Notes:
1. The QHF-3 series covers 30 MHz to 1 GHz using a multi-section
stripline design to produce wide operating bandwidths. Designs
for many other frequency ranges are available to custom order.
2. High performance is achieved in the QHF-3 series using the
Filmbrid™ Sandwich Package that’s designed to work with both
microstrip and balanced stripline.
