Abstract
Design tables for broadband terminations are presented. The termination circuits consist of one or two ?/4 transmission lines in cascade loaded with a resistance in series with an open circuit stub. Since no holes in the substrate or metallic connections with the groundplanes are needed the design is suitable for printed circuits. Measurements have been made on a termination which had a total length of ?/2. The bandwidth was designed to be 85 percent. The experimental result is close to the theoretical predictions. Broadband terminations of this kind may be used in a number of ways. An example of a broadband modified Pi-attenuator without a ground connection is included.

Theory and Design of Broad-Band Nongrounded Matched Loads for Planar Circuits (Short Paper)

TL;DR: In this paper, a filter theory approach is used for the synthesis of very broad-band resistive terminations with no direct grounding, and the immediate use is in microwave integrated circuits (MIC's) where no holes or wraparound straps are desirable.

A Very Broadband Matched Termination Utilizing Non-Grounded Radial Lines

TL;DR: In this paper, a very broadband termination using radial lines in a "shamrock" configuration has been developed, achieving a much wider bandwidth than adopting both a conventional straight stub and an "half-moon" configuration.

Accurate and Process-Tolerant Resistive Load

TL;DR: In this article, a new resistive network that compensates for the high-frequency parasitic effects of the resistors to improve the bandwidth of the termination is proposed, in addition to maintaining accuracy, the presented network provides tolerance to variation in the resistor values.

Termination with Stubs in Resistive Film

TL;DR: In this paper, the authors proposed a novel termination with stubs in resistive film, which can disperse heat by resonating an input signal with open stubs and improved surface loss density by 50% compared to the conventional one.
