An amplifier circuit amplifies a signal for wireless transmission. A feedback circuit, including a capacitor, is coupled to the amplifier circuit. Components of the feedback circuit are selected based on a feedback factor such that an input impedance to the amplifier circuit has a same impedance characteristic as a feedback circuit impedance of the feedback circuit.

An automatic antenna impedance matching method for a radiofrequency transmission circuit. An impedance matching network is inserted between an amplifier and an antenna. The output current and voltage of the amplifier and their phase difference are measured by a variable measurement impedance, and the complex load impedance of the amplifier is deduced from this; the impedance of the antenna is calculated as a function of this complex impedance and as a function of the known current values of the impedances of the matching network. Starting from the value found for the impedance of the antenna, new values of the matching network are calculated that allow the load to be matched to the nominal impedance of the amplifier. The measurement impedance has a value controllable by the calculation processor according to the application and notably as a function of the operating frequency and of the nominal impedance of the amplifier.

In one embodiment, a server of a first wireless communication network receives a wireless communication originated by a terminal of the first wireless communication network, the wireless communication containing a current geographic location of the terminal as determined by the terminal. The server may then determine acceptable communication parameters for the terminal to communicate on the first wireless communication network, e.g., based on preventing transmission by the terminal that might interfere with operation of one or more unintended receivers. The server then generates an instruction message for the terminal based on the acceptable communication parameters, and transmits the instruction message toward the terminal to cause the terminal to only continue transmitting according to acceptable communication parameters.

In one embodiment, a device of a first wireless communication network determines a link budget from a terminal in the first communication network to an unintended receiver for a communication from the terminal to an intended receiver in the first wireless communication network, based on the communication being configured with initial communication parameters. The device also determines whether one or more adjusted communication parameters would result in reducing a received power at the unintended receiver being below a link budget threshold, while still satisfying a receive sensitivity of the intended receiver. If so, the device causes the terminal to transmit the communication using the adjusted communication parameters. In one embodiment, the device is the terminal, and causing comprises transmitting as the terminal. In another embodiment, the device is a server of the first communication network, and causing comprises instructing the terminal to transmit the communication using the adjusted communication parameters.

Monty and Rose met last year on a beach on the north side of Chicago. Their attraction was intense, immediate, and you might say, fruitful. Somewhere between the roll of lake waves and the shimmer of skyscrapers overlooking the beach, Monty and Rose fledged two chicks. They protected their offspring through formative times. But then, in fulfillment of nature's plan, they parted ways, and left the chicks to make their own ways in the world. Monty and Rose are piping plovers, an endangered species of bird of which there may only be 6,000 or 7,000 in the world, including Monty, Rose and their chicks. They were the first piping plovers to nest in Chicago in more than 60 years. After their chicks fledged, they drifted apart. Rose went off to Florida for the winter, and Monty made his way to the Texas coast. They'd always have the North Side, but were each on their own in a huge, fraught world. And then, just a few days ago, Monty and Rose were sighted again, on the same patch of sand on

This week, we have a conversation with A&R man, producer, and all-around Renaissance man Dante Ross. Ross has had an instrumental role in the careers of acts like Ol’ Dirty Bastard, Busta Rhymes, Brand Nubian, Everlast, De La Soul, Del tha Funkee Homosapien, KMD, and tons more. We talked to him about the highlights and wild times of his extensive career.

This episode, we talk to Dan Charnas, industry veteran, prolific music journalist, screenwriter, and most recently author of The Big Payback, the definitive history of hip hop business. Charnas began in the mailroom of the seminal rap label Profile Records, eventually becoming Rap A&R and Promotion Manager — working on projects from Run-D.M.C., Dana Dane, Special Ed, Rob Base, Special Ed and DJ Quik. He was one of the first writers for The Source, part of the movement to create hip hop journalism. He was hired by Rick Rubin to run the rap department of his new Warner Bros joint venture, American Recordings. He went on to play many more roles within and surrounding the hip hop industry, getting deeply involved in projects including Sir Mix-A-Lot’s double-platinum single “Baby Got Back”, DJ Kool’s gold anthem “Let Me Clear My Throat,” and Chino XL’s acclaimed “Here To Save You All”.

As an incredibly talented writer and incredibly savvy man, Charnas set out about 4 years ago to begin constructing a complete history of hip hop business. What began as a potential news article quickly took a life of its own and this year he finally saw the completion of his work, acclaimed by the New York Times as “epic” and by Forbes as “a mature, Pulitzer-worthy work, an integral account of essential urban history”. The book contains detailed accounts of major transitions and deals made within the hip hop industry that would shape the music landscape for years to come.

We talk the dichotomy between being rich and being real, black capital in America, Bronx based beat hip hop vs. DJ Hollywood’s “club rap”, and more.
