  • Signal Issue 35
    Signal Issue 35 Tricks of the Trade Dave Porter G4OYX and Alan Beech G1BXG We continue to celebrate the 50th anniversary of the start of offshore commercial radio in the UK and are now in June 1965. By this time, the number of stations on the air was increasing steadily, taking advantage of the (lack of) laws at the time with regard to operations in International Waters. The first two stations, Caroline and Atlanta, had used 10 kW AM transmitters by Continental Electronics employing their patented version of screen grid modulation but, just prior to Christmas 1964, the US-inspired and -built station of Radio London on the former US minesweeper USS Density renamed M/V Galaxy was on the air with test transmissions on 266 m, 1124 kHz, running, at first, 17 kW. This 50 kW transmitter was an RCA BTA-50H and was the first of many in the offshore fleet to employ the ‘Ampliphase’ approach. From ‘outphasing’ to ‘Ampliphase’ Amplitude from phase The theory of what became known as ‘Ampliphase’ was The principle of ‘Ampliphase’ is to take a single frequency proposed and developed in France by Henry Chireix in drive source, split it into two feeds, phase modulate each 1935 who called the technique ‘outphasing’. feed, amplify as required and add the two signals in a combining network. Amplitude modulation is achieved by ‘Outphasing’ was not taken up initially by RCA but by the degree of addition or subtraction due to the phase McClatchy Broadcasting in the late 1940s, first at KFBK, difference between the two signals.

  • Hans Knot International Radio Report April 2016 Welcome to Another
    Hans Knot International Radio Report April 2016 Welcome to another edition of the International Radio Report. Thanks all for your e mails, memories, photos, questions and more. Part of the report is what was left after the March edition was totally filled and so let’s go with this edition in which first there’s space for a story I wrote last months after again doing some research: ‘Ronan O’Rahilly, Georgie Fame and the Blue Fames. Where it really went wrong!’ On this subject I’ve written before but let’s go back in time and also add some new facts to it: ‘Was Ronan O’Rahilly the manager of Georgie Fame?’ I can tell you there was a problem with an important instrument. When in April 1964 Granada Television came with an edition of the ‘World in action’ series, which was a production from Michael Hodges, they informed the television public about a new form of Piracy, the watery pirates. Two radio ships bringing music and entertainment under the names of Radio Caroline and Radio Atlanta. Radio Caroline was the first 20th century Pirate off the British coast with programs, at that stage, for 12 hours a day. Interviews with the Caroline people were made in the offices of Queen Magazine in the city of London and included – among others – Jocelyn Stevens and the then 23-year old Irish Ronan O’Rahilly. During this documentary it became known, which we would also read in several newspapers in the then following weeks, that Ronan O’Rahilly had started his radiostation Caroline as he couldn’t get his artists played on stations like Radio Luxembourg.

  • Theory and Implementation of RF-Input Outphasing Power Amplification Taylor W
    1 Theory and Implementation of RF-Input Outphasing Power Amplification Taylor W. Barton, Member, IEEE, and David J. Perreault, Fellow, IEEE Abstract—Conventional outphasing power amplifier systems require both an RF carrier input and a separate baseband input to synthesize a modulated RF output. This work presents an RF-input / RF-output outphasing power amplifier that directly amplifies a modulated RF input, eliminating the need for multiple costly IQ modulators and baseband signal component separation as in previous outphasing systems. An RF signal decomposition network directly synthesizes the phase- and amplitude-modulated signals used to drive the branch PAs. With this approach, a modulated RF signal including zero-crossings can be applied to (a) Digital SCS the single RF input port of the outphasing RF amplifier system. The proposed technique is demonstrated at 2.14 GHz in a four- way lossless outphasing amplifier with transmission-line power combiner. The RF decomposition network is implemented using a transmission-line resistance compression network with nonlinear loads designed to provide the necessary amplitude and phase decomposition. The resulting proof-of-concept outphasing power amplifier has a peak CW output power of 93 W, peak drain efficiency of 70%, and performance on par with a previously- demonstrated outphasing and power combining system requiring four IQ modulators and a digital signal component separator. (b) RF-domain SCS (this work) Index Terms—base stations, outphasing, power amplifier (PA), Fig. 1.
