Claims
- 1. A balanced video detecting device, comprising a detecting element in the form of a superconducting film, the film having a first end, a second end, and a center, means for inputting a signal to be detected from a first antenna to the first end and means for inputting the signal to be detected from a second antenna to the second end, means for applying a DC bias current to said detecting element for causing the DC bias current to flow unidirectionally between the first and second ends, and means approximately at the center of the film for obtaining a balanced video output.
- 2. A balanced video detecting device according to claim 1, wherein the thickness d.sub.o and width w.sub.o of the film satisfy the following equations: ##EQU4##
