Nuevo amplificador 4O3A - Power Genius XL - SO2R

Avanzado puede ser pero es feo, feo.

Y los mandos son cutres.

No hay duda que el diseño exterior es... diferente.
Por que tu sabes que para esto de los gustos... hay de todo.

Tiene cierto aire con aquellos estabilizadores de tensión de hace años, que se les ponían a las teles. Pues creo que eran con un diseño similar, con esa rejilla frontal, etc.

Ese estilo debe estar de moda por Montenegro...

Hola,

Ya sabíamos que Flex y 4O3A habían llegado a un acuerdo de colaboración el año pasado.
Al parecer, fruto de ese acuerdo es este amplificador, y parece ser que Flex va a ser el único distribuidor oficial y exclusivo, como "amplificador oficial" de los Flex 6000.

Desconozco si 4O3A lo vendería también, o por lo menos aquí en Europa.

Lo siguiente es sólo un extracto del comunicado:

Parecería que el ampli nuevo les ha gustado tanto a los de Flex que han decido quedarselo, y venderlo con su marca y todo.

Aquí se ve al ampli por dentro, en pruebas;

Hola,

Después de las críticas recibidas por el diseño exterior del prototipo, parece que se han esmerado en el diseño exterior tanto como en el interior, y este parece ser el resultado final;

Preparar la cartera...

PowerGenius XL™ is a true legal limit, all mode, HF -6m solid state
amplifier in a small lightweight package incorporating the very latest
in LDMOS transistor technology.

PowerGenius XL obsoletes those heavy and expensive to maintain tube
amplifiers even in the most demanding DX and contest operations. Born of
the collaboration between Sky Sat’s 403A Signature Laboratory in Europe
and Austin, Texas based FlexRadio Systems, the PowerGenius XL joins
decades of HF amplifier and RF system engineering experience to deliver
unique, proprietary design features built with state-of-the-art
components for unrivaled performance.

√ Full legal power HF -6m, *1500W* ICAS, all mode with *2000W* headroom
√ Unique Maximum Efficiency Algorithm (MEffA™) for efficiencies up to 75%
√ Diplexed filters maximize harmonic suppression and efficiency
√ Fully SO2R capable – 70dB nominal isolation between exciter inputs
√ Automatic Power Control (APC) for ultra fast SWR protection
√ Remote control with desktop application in LAN or WAN networks

The PowerGenius XL is a 100% duty cycle, legal limit (1500W ICAS)
1.8-54MHz RF amplifier intended for both amateur and government use. It
incorporates a pair of modern NXP 1K5H LDMOS transistors that are
individually capable of 1.5 KW thus providing plenty of headroom for
lowest IMD and spurious output. Efficiency and spurious performance are
also enhanced through the use of diplexed filters.

Multiple band selection methods are supported including CAT, CI-V, BCD
band decode and Ethernet to allow automated operation with most modern
radios. When connected to a FLEX-6000 Series radio over Ethernet,
SmartSDR™ provides fully integrated station automation. To simplify
integration, T/R control is provided over the Ethernet connection which
further minimizes wiring. In addition, all amplifier status reporting,
including power levels, fault conditions and resets are reported to the
FLEX-6000 series transceiver using the SmartSDR API. SmartSDR client
interfaces such as SmartSDR for Windows®, Maestro™ and others can
display power levels and other reported statuses.

For remote operation and other RF radio exciters, an Ethernet API or
friendly Windows® or Android™ app can control the PowerGenius XL. For
contest operation, the PowerGenius XL is SO2R capable with two inputs
and two outputs for two sources and antennas and the rapid band
switching eliminates the need for two amplifiers. A single FLEX-6700 and
PowerGenius XL comprises a complete SO2R station at half the cost of
competing solutions.

*UNIQUE FEATURES OF POWERGENIUS XL*
PowerGenius XL provides unprecedented performance in your shack while
providing cost savings over other competing solutions. Unique to
PowerGenius are the following features:

Dual Filtering
/PowerGenius XL’s dual filtering capability provides for exceptionally
clean spectrum./
√ Diplexer for each band routes fundemental frequency through a Low Pass
Filter (LPF) and harmonics to a 50 Ohm load.
√ All harmonics are significantly suppressed beyond strict FCC and CE
regulations.
√ Harmonic energy goes through two stages of reduction.

/MEffA™ = Unparalled Efficiency/
√ Patent pending Maximum Efficiency Algorithm (MEffA)
√ For single tone modes (CW, RTTY), MEffA sets dynamic real time output
device drain voltage and current yielding maximum efficiency for output
power in real time, reducing heat dissipation for efficiency up to 75%.
√ Up to 65% efficiency with excellent IMD characteristics for SSB.

/Automatic Power Control (APC)/
√ When high VSWR is detected, APC proportionately reduces output power
to a safe level allowing for continued operation.
√ When VSWR exceeds high limit, APC switches to STBY mode.
√ When APC detects increased heat sync temperature, it will reduce the
output power only if the MEffA system can not contain it within allowed
limits; when the amp cools to a safe 60º C, APC will return amp back to
full power.
√ Protection reacts in a time frame of about 1 μs to protect the
amplifier from high VSWR and temperature.

Es curioso que no le hayan incluido un acoplador automático, como si lo tienen los de SPE.

Me parece un juguete interesante pero por ahora me sigue gustando mas los SPE justo por eso que este no tiene.
