Abstract
A transmission-type phase-shift attenuator has a poor reflection chara cteristic at an output port. In this paper, to avoid such disadvantage s, a reflection-type low-phase shift attenuator has been designed and measured. As a result, at a center frequency (1855 MHz), the reflectio n-type low-phase shift attenuator has an attenuation of 30 dB, within the limit of 30 phase shift and less than -17-dB reflection characteri stics at both input and output ports. It also demonstrates that the pe rformance of the reflection-type low-phase-shift attenuator is better than the transmission-type phase-shift attenuator with the same measur ement specifications.
