Title:
ULTRA-WIDE-BAND MEASUREMENT BRIDGE
Document Type and Number:
WIPO Patent Application WO/2013/164453
Kind Code:
A3
Abstract:
A measurement bridge (1) has a first matching member (2), a second matching member (3) and a third matching member (4), wherein each of said matching members (2, 3, 4) consists of at least three resistors (21, 22, 23, 31, 32, 33, 41, 42,43), which are arranged in respective T-structures. A second resistor (32) of the second matching member (3) is connected to a second resistor (22) of the first matching member (2), and a third resistor (43) of the third matching member (4) is connected to a third resistor (23) of the first matching member (2). A second resistor (42) of the third matching member (4) can be connected to a measurement object (7). A third resistor (33) of the second matching member (3) can be connected to a calibration standard (5), and a first resistor (31, 41) of the second and third matching members (3, 4) are connected to a respective signal input of a component (11) that suppresses a common-mode part on the two signal inputs thereof.
