Abstract
Microwave ports and low-frequency ports of a microwave enclosure are configured to realize high return losses and low insertion losses and suppress resonance modes below a predetermined microwave frequency. The microwave ports include microwave transmission lines which have first and second microstrip portions and a stripline portion which connects the first and second microstrip portions. The microwave transmission lines are positioned with the stripline portion received in a housing aperture. The low-frequency ports include a dielectric member and a plurality of metallic signal lines carried within the dielectric member. The dielectric member is relieved to expose inner and outer ends of the signal lines. The connector systems are received in housing apertures with metallic members positioned through the dielectric members and across the connector apertures to electrically partition the connector apertures into subapertures which each have a predetermined microwave cutoff frequency.
