Jan 12, 2009

Appl. No.:

12/319898

Inventors:

Yang Li - Cambridge MA, US
Robert Broughton - Chester NH, US
James Bonkowski - Cary IL, US
Peter Bacon - Derry NH, US

Assignee:

Peregrine Semiconductor Corporation - San Diego CA

International Classification:

H03F 3/68

US Classification:

330129, 330 51

Abstract:

An RF PA operable in two or more selectable power ranges is disclosed. Switches configure the circuit for each range such that an amplifier device corresponding to the range provides final amplification, and all lower power amplifier devices also amplify the signal. An exemplary design includes a low power amplifier configurable for operation solo, or in parallel with a medium power amplifier, to deliver an appropriately matched signal either directly to the RF PA output, or first to the input of a high power amplifier for the highest power range. The signal in all ranges of the exemplary design is conditioned in part by the matching circuitry disposed between the high power amplifier and the RF PA output, which traverses no switches in high power range operation. The entire RF PA, including switches, control and matching circuitry, is fabricated on a single monolithic integrated circuit, an achievement may be facilitated by UTSI CMOS processing.

International Classification:

G06F 3/00

US Classification:

715863, 715811, 715812, 715745, 715708

Abstract:

In one example, a method includes receiving, by a server and from a plurality of computing devices, data representative of a group of gesture-shortcut pairs that each include a gesture having been detected by at least one computing device from the plurality of computing devices and a shortcut associated with the detected gesture, and wherein the shortcut corresponds to an operation to be executed by the at least one from the plurality of computing devices. The method includes sorting the data representative of each respective gesture-shortcut pair from the group of gesture-shortcut pairs into at least two subgroups, a first subgroup including the first gesture-shortcut pair and a second including the second gesture-shortcut pair, the sorting being based on detected similarities between at least one of each respective gesture from the group of gesture-shortcut pairs and each respective shortcut from the group of gesture-shortcut pairs.

Abstract:

A sandwich strip coupled coupler implemented in a multi-layer substrate, such as a multi-layer printed circuit board. In one example, the sandwich strip coupled coupler includes a main arm having a first main arm section and a second main arm section disposed above the first main arm section, the first and second main arm sections being electrically connected together, and a coupled arm disposed between the first and second main arm sections, the first main arm section, the coupled arm and the second main arm section forming a sandwich structure.

Assignee:

Peregrine Semiconductor Corporation - San Diego CA

International Classification:

H03F 3/04

US Classification:

330311, 330310

Abstract:

A power amplifier with stacked, serially connected, field effect transistors is described. DC control voltage inputs are fed to the gates of each transistor. Capacitors are coupled to the transistors. The inputs and the capacitors are controlled to minimize generation of non-linearities of each field effect transistor and/or to maximize cancellation of distortions between the field effect transistors of the power amplifier in order to improve linearity of the power amplifier output.

US Classification:

327564, 333136, 29854

Abstract:

A coupler is presented that has high-directivity and low coupling coefficient variation. The coupler includes a first trace associated with a first port and a second port. The first port is configured substantially as an input port and the second port is configured substantially as an output port. The coupler further includes a second trace associated with a third port and a fourth port. The third port is configured substantially as a coupled port and the fourth port is configured substantially as an isolated port. In addition, the coupler includes a first capacitor configured to introduce a discontinuity to induce a mismatch in the coupler.
