PowerGenius XL\u2122 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.<\/p>\n

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\u2019s 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.<\/p>\n

\u221a Full legal power HF -6m, 1500W<\/strong> ICAS, all mode with 2000W<\/strong> headroom
\n\u221a Unique Maximum Efficiency Algorithm (MEffA\u2122) for efficiencies up to 75%
\n\u221a Diplexed filters maximize harmonic suppression and efficiency
\n\u221a Fully SO2R capable – 70dB nominal isolation between exciter inputs
\n\u221a Automatic Power Control (APC) for ultra fast SWR protection
\n\u221a Remote control with desktop application in LAN or WAN networks<\/p>\n

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.<\/p>\n

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\u2122 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\u00ae, Maestro\u2122 and others can display power levels and other reported statuses.<\/p>\n

For remote operation and other RF radio exciters, an Ethernet API or friendly Windows\u00ae or Android\u2122 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.<\/p>\n

UNIQUE FEATURES OF POWERGENIUS XL<\/strong>
\nPowerGenius XL provides unprecedented performance in your shack while providing cost savings over other competing solutions. Unique to PowerGenius are the following features:<\/p>\n

Dual Filtering<\/span>
\nPowerGenius XL\u2019s dual filtering capability provides for exceptionally clean spectrum.<\/em>
\n\u221a Diplexer for each band routes fundemental frequency through a Low Pass Filter (LPF) and harmonics to a 50 Ohm load.
\n\u221a All harmonics are significantly suppressed beyond strict FCC and CE regulations.
\n\u221a Harmonic energy goes through two stages of reduction.<\/p>\n

MEffA\u2122 = Unparalled Efficiency<\/em>
\n\u221a Patent pending Maximum Efficiency Algorithm (MEffA)
\n\u221a 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%.
\n\u221a Up to 65% efficiency with excellent IMD characteristics for SSB.<\/p>\n

Automatic Power Control (APC)<\/em>
\n\u221a When high VSWR is detected, APC proportionately reduces output power to a safe level allowing for continued operation.
\n\u221a When VSWR exceeds high limit, APC switches to STBY mode.
\n\u221a 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 60\u00ba C, APC will return amp back to full power.
\n\u221a Protection reacts in a time frame of about 1 \u03bcs to protect the amplifier from high VSWR and temperature.<\/p>\n
