摘要： A distributed cell field-effect transistor (FET) amplifier (40) includes a plurality of parallel, elongated source (46a) and drain (46b) regions of individual FET unit cells (46) formed in a substrate (42) in transverse alternating relation, with a plurality of elongated channel regions (46c) being formed between and parallel to adjacent source (46a) and drain (46b) regions respectively. A source foot (48) and a drain foot (50) extend perpendicular to the source (46a) and drain (46b) regions on opposite longitudinally spaced sides thereof respectively. A gate foot (52) extends parallel to the source (48) and drain (50) feet, between the source foot (48) and the cells (46). Source (54) and drain (56) pads and gate (58) fingers extend from the source (48), drain (50) and gate (52) feet into electrical connection with the respective source (46a), drain (46b) and gate ( 46c) regions respectively. The source pads (54) include airbridge portions (54b) which extend over the gate foot (52) without making contact therewith. A fixed tuning circuit (70) is connected between the gate foot (52) and source foot (48), including an inductive stub (72) having a first end connected to the gate foot (52) and a second end, and a capacitor (74) having a first plate (74a) which is integral with the source foot (48) and a second plate connected to the second end of the stub (72). The integration of the capacitor (74) with the source foot (48) enables the amplifier (40) to be tuned at the gate foot (52), thereby eliminating undesirable coupling effects and the need for a separate via for the tuning circuit (70).

摘要： A new concept of power amplifying apparatus and method is developed for adopting pre-distortion and applying to a radio communication system. The power amplifying apparatus includes a pre-distortion module for pre-distorting an input signal x(n) according to a pre-distortion function, and for outputting a pre-distorted signal z(n), a power amplifier for amplifying a signal obtained by digital-to-analog conversion of the pre-distorted signal z(n), a pre-distortion function producing module for receiving the pre-distorted signal z(n) and a signal y(n) obtained by analog-to-digital conversion of the fed-back output signal of the power amplifier, and for obtaining model coefficients cq,k,s that minimize the power of a modeling error signal e(n)=z(n)−y(n). The pre-distortion function used by the pre-distortion module is represented as z ⁡ ( n ) = ∑ q = 0 Q ⁢ ∑ k = 1 K ⁢ ∑ s = - S min ⁢   ⁢ ( S , q ) ⁢ c q , k , s ⁢ y ⁡ ( n - q + s ) ⁢  y ⁡ ( n - q )  k - 1 .

摘要： In some embodiments, a graphical user interface (GUI) of a computer security application is automatically configured according to a user profile of the user. Upon installation of the computer security application, a desired GUI complexity questionnaire is displayed to the user. The application then matches the user to a user profile out of a set of predefined user profiles, according to the user's answers to the questionnaire. User profiles reflect a user's desired complexity of display and control (e.g. Novice/Intermediate/Expert, Basic/Intermediate/Advanced). The information displayed and application controls provided by the GUI window vary in detail according to the user profile. Selecting a user profile propagates multiple individually-user-configurable display and control settings of the GUI, as well as under-the-hood (non-GUI) settings of the anti-malware application.

摘要： A mechanism that enables flexible expansion of proxy firewall services is disclosed. In accordance with the present invention, the firewall system can be configured to include a dispatch host computer and one or more load host computers. Proxy firewall services can be provided by proxy applications that reside on either the dispatch host computer and/or the load host computers. In one embodiment, a load host computer can be configured to support multiple proxy applications. In other embodiments, a load host computer can be dedicated to a single resource intensive application. In this framework, a network administrator can flexibly decide how to accommodate the demand for proxy firewall services. Load hosts can be added or removed from the firewall system without disrupting ongoing security services. In one embodiment, this feature is enabled through the inclusion of a configuration file on the dispatch host computer that stores information relating to the load host computers in the firewall system.
