Filed:

Jan 26, 2015

Appl. No.:

14/605759

Inventors:

- Carlton, AU
Antonio Torrini - Austin TX, US
Natalino Camilleri - Cupertino CA, US

International Classification:

H01Q 3/24

Abstract:

An approach is provided for managing power consumption in mobile devices configured with a plurality of directional antenna elements and a radio frequency integrated circuit (RFIC). The RFIC is configured to select for use, by the mobile device, a first set of one or more directional antenna elements from the plurality of directional antenna elements based upon selection criteria that include at least one or more power consumption criteria and one or more of one or more performance criteria or one or more interference avoidance criteria.

Inventors:

- Fitzroy, AU
Natalino Camilleri - Cupertino CA, US

International Classification:

H03G 1/00
H03B 5/08
H01G 7/00

Abstract:

An apparatus with a multi-varactor circuit for suppressing VCO gain is described herein. According to an embodiment, the apparatus comprises a plurality of varactor stages that are electrically coupled in parallel. For two or more varactor stages of the plurality of varactor stages, each respective varactor stage of the two or more varactor stages includes a set of one or more varactors that are electrically coupled to a tuning source. Each respective varactor stage of the two or more varactor stages is configured to vary a respective capacitance based on a tuning voltage from the tuning source and to be biased at a different respective voltage level. In other embodiments, the set of one or more varactors for each varactor stage of the two or more varactor stages includes at least one digitally-controlled switched varactor. The digitally-controlled switched varactors may be selectively connected to the tuning source.

International Classification:

H01Q 3/24
H04B 1/40

Abstract:

An apparatus for reducing interference and improving communication quality for RF communications over mm-wave frequency bands between wireless communications devices. In one embodiment, for example, the apparatus comprises a plurality of high-gain directional antenna elements each configured to maximally radiate in different directions relative to the apparatus. The apparatus also includes a RFIC chip electrically coupled to the plurality of antenna elements and configured to switch from driving any one of the directional antenna elements to driving another of the directional antenna elements thereby providing a multi-directional or near omni-directional radiation capability for a wireless communications device.
