23 Jan 2007TL;DR: In this paper, a power amplifier (PA) is coupled with a matching circuit, where the first and second matching circuits maintain the PA output voltage at a value no more than a predetermined maximum value, which is less than a breakdown voltage.
Abstract: Power amplifier (PA) apparatus (300) that includes: a PA device (302) operating at a fundamental frequency and having a maximum operating frequency that is higher than the fundamental frequency, an output current having a fundamental component at the fundamental frequency and a plurality of harmonic components at different harmonic frequencies of the fundamental frequency, and an output voltage based on the output current; a first matching circuit (310) coupled to the PA device and corresponding to the fundamental component; and a second matching circuit (320) coupled between the PA device and the first matching circuit and corresponding to at least one of the harmonic components, wherein the first and second matching circuits maintain the PA output voltage at a value that is no more than a predetermined maximum value, which is less than a breakdown voltage for the PA device.

06 Aug 2013TL;DR: In this paper, a very-low intermediate frequency (VLIF) receiver and a method of controlling a VLIF receiver is presented, which comprises receiving a first signal, the first signal including a first adjacent channel interferer, and detecting first interference from the first adjacent channels interferer.
Abstract: A very-low intermediate frequency (VLIF) receiver and a method of controlling a VLIF receiver. The method comprises receiving a first signal, the first signal including a first adjacent channel interferer, and detecting first interference from the first adjacent channel interferer. The method further comprises, subsequent to receiving the first signal, receiving a second signal, the second signal including a second adjacent channel interferer, and detecting second interference from the second adjacent channel interferer. Furthermore, subsequent to detecting the second interference, the VLIF receiver is configured to avoid the first interference while receiving a third signal.

13 Jan 1992TL;DR: In this paper, an image projection system utilizing a cold cathode field emission device to provide the image source is provided, where an improved image may be achieved as compared to that of a conventional electron-gun CRT image source.
Abstract: An image projection system utilizing a cold cathode field emission device to provide the image source is provided. By using a cold cathode field emission device as an image source, an improved image may be achieved as compared to that of a conventional electron-gun CRT image source. First, the resulting image provides improved resolution, due to the fact that smaller pixel cells may be achieved with the cold cathode device. Second, the resulting image is considerably brighter, due to the fact that much higher current densities are achievable with a cold cathode image unit, as compared to the older electron-gun CRT unit.

29 Sep 2006TL;DR: In this article, an apparatus and method for eliminating unwanted signal power dissipation in balanced amplifier circuits and for prohibiting unwanted signal powers from appearing at the balanced amplifier load is presented, where load impedances to the amplifier power output transistors are maintained very low at unwanted frequencies.
Abstract: An apparatus and method for eliminating unwanted signal power dissipation in balanced amplifier circuits and for prohibiting unwanted signal power from appearing at the balanced amplifier load is presented. Load impedances to the amplifier power output transistors are maintained very low at unwanted frequencies, and are at an operational impedance level at the fundamental frequency. An impedance network control concept is presented, which may be either manually or automatically implemented.

30 Nov 2006TL;DR: In this article, a small volume antenna (100) has the form of a polygonal board with multiple antenna elements (104, 110) located at vertices (114, 116) (e.g., opposite vertices).
Abstract: A small volume antenna (100) has the form of a polygonal (e.g., square) board with multiple antenna elements (104, 110) located at vertices (114, 116) (e.g., opposite vertices). The antenna elements (104, 110) include two segments (118, 120, 124, 126) that meet at corners (122, 128) that are located at the vertices (114, 116). Peripheral portions (134, 136, 138, 140) of a ground plane (132) that underlie the segments (118, 120, 124, 126) of the antenna elements are deleted, and slots (154, 162) that have two joined segments (156, 158, 164, 166) that parallel the segments (118, 120, 124, 126) of the antenna elements (104, 110) are formed in the antenna elements. The antenna elements (104, 110) are selectively loaded by switched impedance (e.g., capacitance) networks (172, 176, 178, 180, 182, 186, 190, 192). The antenna (100) is able to support operation in at least two broad operating bands.
