Abstract

A direct RF undersampling reception has been focused to realize compact and low power consumption receiver. This architecture requires a higher gain LNA than the conventional one. In this paper, we fabricate a Ku-band direct RF undersampling receiver together with a power switching (intermittent-mode) LNA to reduce the power consumption. The DC power of intermittent-mode LNA turns off during the hold period of S/H circuit. As a result, DC power consumption of the LNA can be reduced to 1/2 without the degradation of reception performance. We have measured the performances of fabricated receiver and have confirmed the effect of intermittent-mode LNA usage.
