Patent number: 8094704Abstract: Systems and methods of detecting wireless channel status from acoustic discrimination of spectral content are described. In one aspect, a wireless system includes a spectrum analyzer, a detector, and a controller. The spectrum analyzer is operable to acoustically discriminate spectral content of an input electrical signal in multiple discrete frequency channels. The detector is operable to determine respective statuses of the frequency channels from the acoustically discriminated spectral content. The controller is operable to select one of the frequency channels based on the determined statuses of the frequency channels.Type: GrantFiled: September 15, 2005Date of Patent: January 10, 2012Assignee: Avago Technologies Wiresless IP (Singapore) Pte.

Patent number: 8058933Abstract: A first and a second resonator are fabricated monolithically adjacent to one another. The first resonator is the reference resonator. The resonant frequency of the second resonator is offset by a difference frequency Fo from the first resonator. Each resonator is included within an oscillator. A mixer receives the output of both oscillators. A low pass filter receives the mixer output and generates a clock signal whose frequency is equal to the difference frequency Fo.Type: GrantFiled: September 21, 2005Date of Patent: November 15, 2011Assignee: Avago Technologies Wireless IP (Singapore) Pte.

Patent number: 7391286Abstract: A film acoustically-coupled transformer (FACT) has a first and a second stacked bulk acoustic resonator (SBAR 1, SBAR 2). Each SBAR has a stacked pair of film bulk acoustic resonators (FBARs) and an acoustic decoupler between the FBARs. Each FBAR has opposed planar electrodes and a layer of piezoelectric material between the electrodes. A first electrical circuit connecting one of the FBARs of SBAR1 to one of the FBARs of SBAR 2 and a second electrical circuit connecting the other of the FBARs of SBAR 1 to the other of the FBARs of SBAR 2. The first electrical circuit connects the respective FBARs in parallel and second electrical circuit connects the respective FBARs in series. A shunt inductor is included from the reception path to ground.Type: GrantFiled: October 6, 2005Date of Patent: June 24, 2008Assignee: Avago Wireless IP Pte LtdInventors: Tiberiu Jamneala, Michael Louis Frank, Paul D Bradley

Patent number: 7383032Abstract: A cellular phone and method for receiving and transmitting signals of different frequency bands and wireless standards utilizes an architecture that allows the use of switches that are less expensive and less lossy than switches used in comparable cellular phones. The architecture also allows the use of only narrow-banded antennas, rather than a combination of a narrow-banded antenna and a harmonic antenna. As a result, the performance of the cellular phone can be significantly improved.Type: GrantFiled: December 2, 2004Date of Patent: June 3, 2008Assignee: Avago Technologies Wireless IP Pte LtdInventors: Michael Louis Frank, Allen Tze-Chung Chien

Patent number: 7383024Abstract: Architectures for a class of multi-band handsets are described. These architectures separate linearity requirements from isolation requirements and reduce the number of throws on switches requiring linearity through the use of distributed switching, filter structure placement between the switch functions, not sharing a power amplifier between frequency bands that have a Tx to Rx overlap, and simplifying the switching structure using filtering networks or multiple antennas.Type: GrantFiled: September 30, 2005Date of Patent: June 3, 2008Assignee: Avago Technologies Wireless IP Pte LtdInventors: William Carrol Mueller, Michael Louis Frank

Patent number: 7187255Abstract: A filter and method of manufacturing a filter having a lattice arrangement that efficiently utilizes substrate space. An embodiment of the invention is directed to a filter having a plurality of resonators disposed on a substrate, each resonator comprising a first electrode and a second electrode disposed vertically adjacent such that an acoustic cavity of a piezoelectric material is formed between each first electrode and each second electrode of each resonator, the first and second electrodes of each resonator electrically isolated from each other via the piezoelectric material. In this manner, the filter is realized without having to use any vias. Additionally, the resonators may be of a shape that allows each to be disposed close together such that some sides of each of the resonators are parallel to each other. Thus, substrate space can be preserved even further.Type: GrantFiled: October 26, 2004Date of Patent: March 6, 2007Assignee: Avago Technologies Wireless IP (Singapore) Pte.

Patent number: 7187062Abstract: The present invention is a coupler built on a semiconductor substrate, e.g. GaAs. Semiconductor processing allows for small trace and space rules. The tighter design rules provide for tighter coupling than can be achieved by ceramic processes. The greater coupling allows for a shorter through line and with less loss, thus closer to ideal coupling.Type: GrantFiled: April 14, 2004Date of Patent: March 6, 2007Assignee: Avago Technologies Wireless IP (Singapore) Pte. Ltd.Inventor: Michael Louis Frank

Patent number: 7162266Abstract: A handset includes two antennae, wherein one antenna is solely dedicated to multi-band frequency division multiplexed signals. The first antenna connects to an antenna switch. The antenna switch further connects to receivers and transmitters of time division band standards. The second antenna transceives a multi-band frequency division multiplexed signal. A modular filter receives the multi-band frequency division multiplexed signal and separates the frequency bands. To provide diversity, the antenna switch connects to a receiver for each frequency division band standard.Type: GrantFiled: December 17, 2004Date of Patent: January 9, 2007Assignee: Avago Technologies Wireless IP (Singapore) Pte.Ltd.Inventor: Michael Louis Frank
