Patent number: 11393619Abstract: A transformer has a first inductor that includes a first port. The transformer also has a second inductor magnetically coupled to the first inductor. The second inductor includes a second port. The second inductor includes a first portion configured to permit current flow in a clockwise direction and a second portion configured to permit current flow in a counter-clockwise direction. The transformer also has a third inductor magnetically coupled to the first inductor. The third inductor includes a third port. The counter-clockwise direction is opposite the clockwise direction to reduce magnetic coupling between the second inductor and the third inductor based on magnetic coupling cancellation.Type: GrantFiled: October 26, 2018Date of Patent: July 19, 2022Assignee: QUALCOMM IncorporatedInventors: Haitao Cheng, Sherif Mahmoud Shakib Roshdy, Abbas Abbaspour-Tamijani, Chinmaya Mishra

Patent number: 10886608Abstract: In an aspect, an apparatus may be an apparatus for wireless communication. The apparatus for wireless communication may include a transceiver, a memory, and at least one processor coupled to the memory and configured to execute instructions stored in the memory to control the transceiver. In another aspect, an apparatus may be an apparatus for wireless communication. The apparatus for wireless communication may include a patch antenna coupled to the transceiver. The patch antenna includes a patch, a ground plane substantially located with respect to the patch, a probe feed coupled to the patch, and a slot-coupled feed configured to couple to the patch.Type: GrantFiled: March 15, 2018Date of Patent: January 5, 2021Assignee: QUALCOMM INCORPORATEDInventors: Jeong II Kim, Jorge Fabrega Sanchez, Mohammad Ali Tassoudji, Abbas Abbaspour-Tamijani, Yu-Chin Ou, Zhang Jin, Thomas Myers

Patent number: 10573950Abstract: Certain aspects of the present disclosure provide a directional coupler. In certain aspects, the directional coupler generally includes a first inductor and a second inductor wirelessly coupled to the first inductor. In certain aspects, the directional coupler generally includes an input port at a first terminal of the first inductor and a transmitted port at a second terminal of the first inductor. In certain aspects, the directional coupler generally includes a coupled port at a first terminal of the second inductor and an isolated port at a second terminal of the second inductor. In certain aspects, the directional coupler generally includes a first complex impedance component directly coupled to the isolated port and a second complex impedance component directly coupled to the coupled port.Type: GrantFiled: April 6, 2018Date of Patent: February 25, 2020Assignee: QUALCOMM IncorporatedInventors: Haitao Cheng, Zhang Jin, Abbas Abbaspour-Tamijani

Patent number: 7724110Abstract: A switchable bandpass filter includes a coupled line segment (comb) including a plurality of coupled transmission lines of substantially equal lengths that are each connected or otherwise coupled to the common RF ground at their first end, a plurality of adjustable capacitors each coupled proximate a second end of respective ones of the transmission lines, and a plurality of shunt switches coupled to points along a length of each of the transmission lines. Shunt switches may be implemented by various device technologies including MEMS and FET switches and PIN diodes. The adjustable capacitors may be implemented as an array or tree of switched capacitors using suitable switching components (e.g., as previously enumerated) or by other suitable electrically controllable devices such as varactors or varactor arrays. A differential switchable filter may be formed by the symmetric repetition of individual bandpass filter modules.Type: GrantFiled: October 1, 2007Date of Patent: May 25, 2010Assignee: Arizona Board of Regents for and on behalf of Arizona State UniversityInventors: Abbas Abbaspour-Tamijani, Masoud Koochakzadeh
