Transmission-line resistance compression networks and related techniques
First Claim
1. A resistance compression network to shape an input impedance at a port for transferring energy to multiple loads at a first frequency, the resistance compression network comprising:
- a first transmission line segment having a first electrical length at the first frequency, the first transmission line segment having an output for coupling to a first load;
a second transmission line segment having a second electrical length at the first frequency, the second electrical length being different from the first electrical length, the second transmission line segment having an output for coupling to a second load; and
a compression port coupled to inputs of both the first and the second transmission line segments;
wherein, over a set of operating conditions of interest, an equivalent resistance looking into the compression port at the first frequency varies over a first resistance range as equivalent resistances of the first and second loads vary over a second resistance range, wherein a range ratio associated with the first resistance range is less than a range ratio associated with the second resistance range, wherein the range ratio of a subject range is a ratio of a largest resistance value in the subject range to a smallest resistance value in the subject range.

Abstract
A resistance compression network to shape an input impedance at a port for transferring energy to multiple loads at a first frequency includes first and second transmission line segments having outputs for coupling to first and second loads and having different electrical lengths at a first frequency and a compression port coupled to inputs of both the first and the second transmission line segments. Over a set of operating conditions of interest, an equivalent resistance looking into the compression port at the frequency varies over a first resistance range as equivalent resistances of the first and second loads vary over a second resistance range and a range ratio associated with the first resistance range is less than a range ratio associated with the second resistance range and the range ratio of a subject range is a ratio of a largest resistance value in the subject range to a smallest resistance value in the subject range.
