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.
