Conference Activities & Talks

Reverse-PIM extraction in non-contact antenna-PIM measurement
Ryosuke Okawa, Nobuhiro Kuga
2017 Asia pacific microwave conference   Nov 2017   IEEE
In this paper, we propose an extraction method of the reverse-PIM component of the direct measurement from the non-contact measurement. To compensate the frequency-dependent mutual coupling between employed antennas, each transmission power is set...
Non-contact PIM measurement of dielectric wave absorbers by using a metallic resonator
Shinji Ishiyama, Nobuhiro Kuga
2017 IEEE MTT-S International Microwave Symposium (IMS)   Jun 2017   IEEE
This paper proposes a non-contact PIM-measurement method for dielectric wave absorbers. It is shown experimentally that the PIM characteristics of a dielectric wave absorber can be measured in an open-ended coaxial tube by mounting a met...
