    摘要: A cable loss simulator for a serial digital signal source adapts a constant resistance, bridged-T passive network to simulate the frequency-loss characteristics of a reference coaxial cable. The cable loss simulator is selectively coupled into the output path of the serial digital signal source to simulate the serial digital signal after transmission through the reference coaxial cable. The cable loss simulator has a resistive input section for impedance matching with the serial digital signal source and a bridged-T section with multiple breakpoints to simulate the frequency-loss characteristic of the reference coaxial cable.

    摘要: A stripline or microstrip feed system distributes electromagnetic power among a set of utilization devices such as the radiators of an array antenna. In the feed system, elongated assemblies of microwave couplers are arranged side by side to provide for a two-dimensional array of couplers corresponding to a two-dimensional array of radiators in rows and columns of an array antenna, and allowing beam steering in a direction perpendicular to the rows. In each assembly of couplers, different forms of couplers are employed to provide both an amplitude taper and a phase taper to the radiations of the respective radiators in each row of radiators. The couplers include the Wilkinson coupler, the hybrid coupler, and the backward wave coupler which serve as power dividers during transmission. There is a feeding of the output signal of one coupler, via a first coupler output terminal to a next coupler in a series of couplers, while the remainder of the power is fed via a second coupler output terminal to a radiator of the antenna. In each coupler assembly there is a main conductor which interconnects a plurality of the couplers to provide a configuration of coupler assembly having a desired narrow width, less than approximately one free-space wavelength.
