Abstract: An electronic cable system operates as an extension cable to facilitate external viewing of internal infrastructure LED status. A wired cable is provided having a first end and a second end, the first end including a first I/O coupler, LED detectors and a power jack; and the second end including a second I/O coupler and a plurality of LEDs. The plurality of LEDs of the second end illuminate in response to activation of the LED detector of the first end. The first I/O coupler may plug into an internal module of electronic infrastructure, such as a server, to detect operational status of the internal module via the LED detectors. The second I/O coupler may couple to infrastructure housing, permitting the plurality of LEDs to be viewed externally of the housing. The plurality of external LEDs on the infrastructure housing mimic internal (non-viewable) status indicator LEDs of the internal module.

Abstract: An electronic control module 100 is provided wherein a power device 102 is secured to a rigidizer, or heat spreader, 110 such that a thermally conductive path is created for a conduction of heat from the power device to the rigidizer. A thermally conductive and electrically insulated interface 208, preferably anodized aluminum, is disposed between device 102 and rigidizer 110 and is solder bonded to each of the device and the rigidizer, facilitating the creation of a thermal path from the device to the rigidizer. In order to solder bond the device to the interface and the interface to the rigidizer, solderable coatings 206, 210, 214 are respectively applied to the surfaces 207 and 209 of the interface and surface 215 of the rigidizer.

Abstract: In a transmitter (200) that includes a radio frequency (RF) power amplifier (218), a predistortion signal loop (234, 240, 209, 208), and a feedforward correction loop (242, 246, 248, 250, 252, 258, 261, 262), a method and apparatus is provided for correcting distortion introduced into the transmitter by the RF power amplifier. The predistortion signal loop determines a RF power amplifier characterization function that characterizes a relationship between a signal input into the RF power amplifier and the resulting signal output by the RF power amplifier. The predistortion signal loop also determines a predistorted input signal that is based on an input signal received from an information source and on the RF power amplifier characterization function, which predistorted input signal is input into the RF power and includes input signal modifications that are meant to compensate for the distortion introduced introduced by the RF power amplifier.

Abstract: Controlling transient responses in power amplifiers may be accomplished in the following manner. Upon detecting an output power adjustment request, a reference level is accessed from memory, wherein the reference level is based on a previous output condition that is substantially equal to the requested output condition. From the reference level, a first response time is calculated and supplied to a control circuit of the power amplifier such that the power amplifier operates at a first gain level. When the first response time elapses, the power amplifier operates at a second gain level, where the first gain level is greater than the second gain level.
