Abstract
In microwave practice, it is often important to measure free-space attenuation of definite radio links or radio systems. These measurements can be accomplished by using a measurement transmitter and a transmitting antenna at one location, and a receiving antenna and a power meter at the second location. Sufficient immunity against reception of parasitic signals that are practically always present in the free-space, especially in relatively densely occupied microwave frequency region, belong among the main problems of such measurements. The designed and realized selective power meter (SPM) solves this problem by using two different filtering methods. Their combination results in a very high selectivity and measurement immunity.
