Abstract:

RF systems configured to implement full-duplex wireless data transfer for rotary joints are disclosed. An example RF system includes a 60 GHz short distance communication link implemented using elliptically (e.g., circularly) polarized antennas. Such a system may provide a mm-wave, high-speed, wideband wireless communication link in a manner that is associated with simpler design and operation, mechanical integrity, and reduced power consumption, compared to alternative solutions.

Abstract:

Customizable tunable filters are provided herein. In certain implementations, a tunable filter including: a first filter bank including a plurality of high-pass filters each having a different cutoff frequency, and a second filter bank including a plurality of low-pass filters each having a different cutoff frequency. The tunable filter further includes a first pair of switches configured to select a first filter chosen from the first filter bank, and a second pair of switches configured to select a second filter chosen from the second filter bank. The tunable filter operates with a first cutoff frequency of the first filter and with a second cutoff frequency of the second filter.
