The disclosure relates to improved filter networks for use in the microwave region employing TTL logic and capable of changing a network from a 'bandpass state' to an 'all-stop state', or an 'all pass state', or from a 'low-pass state' to an 'all pass state'. Provision is also made for the increase or decrease in the selectivity of a low-pass filter.

Integrated electronic controlled diode filter microwave networks

An improved electronic structure for achieving a frequency offset between two or more YIG devices tuned by a single electro-magnet. The structure does not require different sizes of YIG spheres, different magnet gap spacings, or modified coil windings on the electro-magnet, but relies entirely upon the anisotropy variations of the single crystal structure of the YIG spheres when they are mounted on respective tuning rods on a specific axis and rotated under a variable field for a fixed frequency input.
