FLEX-PowerGenius - Amplifier 1.8 to 54 Mhz

The PowerGenius XL is a 100% duty cycle, legal limit (1500W ICAS) 1.8-54 MHz RF amplifier intended for both amateur and government use.  It incorporates a pair of modern NXP MRF1K50H 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.  When connected to a FLEX-6000 transceiver, band selection is fully automated through the Ethernet connection.  Even T/R control is provided over the Ethernet connection to further minimize wiring. In addition, all amplifier status reporting including power levels, fault conditions and resets are reported to the FLEX-6000 Signature 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 with other HF radio exciters, an Ethernet API or friendly Windows and Android applications 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.
