Flexradio Power Genius XL
The PowerGenius XL is a 100% duty cycle, legal limit (1500W ICAS) 1.8-54 MHz RF amplifier. Designed with a pair of the latest NXP MRF1K50H LDMOS transistors that are each capable of 1.5 kW and run up to 2000W easily, providing plenty of headroom for lowest IMD and spurious output.
It has a few first ever features built in:
- MEffA™ system (Maximum Efficiency Algorithm) control efficiency as function of output power. MEffA is a unique technique that changes the DC voltage level to the PA in a manner to match the envelope of the exciting RF in order to yield the most efficiency. The PA efficiency is not constant at a fixed DC level but varies with the envelope of the signal.
- MD precorrector built in, improving IMD for more than 10dB. This makes PG XL the cleanest amplifier on the market.
- Advanced vapor chamber cooling system, first of this in a HAM radio amplifier. Additionally, due to an improvement in material technology we dramatically improved the thermal conductivity.
PG XL is the cleanest amplifer with exceptional spurious performance achieved by its diplexed filters. Thanks to smart cooling, MEffA, real time drive settings and fan speed control PG XL has best thermal performance and lowest fan noise possible.
PG XL is the only fully SO2R capable amplifier. It has 70dB nominal isolation between exciter inputs.
A single FLEX-6700 and Power Genius XL comprises a complete SO2R station at half the cost of competing solutions.
As expected PG XL is well protected from high SWR, with ultra fast SWR circuit, inhibiting RF module in less then 1uS.
