4O3A Signature Power Genius XL Amplificatore hf

4O3A Signature Power Genius XL hf amplifier 1 input and 3 outputs

PowerGenius XL power amplifiers are made of semiconductors and offer up to 2000 watts of peak output power in SSB, or up to 1500W in RTTY and FT-8 at 50% duty cycle. This performance is achieved thanks to the use of two MRF 1K50H LDMOS transistors with an operating voltage of 48 V, which guarantee particularly good linearity and signal purity. The power supply is integrated, processes a single-phase mains voltage of 90 to 250 V AC and is therefore ideal for international operation, for example in DX shipments.

The power amplifier is naturally designed and optimized for remote operation. Depending on the selected variant, the PowerGenius XL is suitable

for connecting up to 3 antennas and a transceiver (3 inputs, 1 output) or

for connecting up to 2 radios for SO2R contest operation (2 inputs, 2 outputs).

For this purpose, a wide range of connections is available: from the bandwidth data connection via Icom CI-V and the CAT serial interface to the Ethernet connection. FlexRadio transceivers, in particular, can be connected with minimal effort (in a simple and intuitive way), but of course any other transceiver can also be used with the PA.

An attenuated 60 dB “pre-distortion” output sends the transmit signal back for analysis and adjustment accordingly, using a suitable transceiver. In this way, maximum spectral purity is achieved and spurious emissions are reduced as much as possible.

The safe and smooth operation of this high-quality amplifier is further simplified by protection mechanisms that protect the output stage and transceiver. Temperature is monitored, alerts are issued if SWR is too high, power is reduced, and much more. A color LCD display provides information on current power and operating status. The only control element is the standby/operation button on the front; everything else works completely automatically. Simple and intuitive.
