This amazing piece of robust engineering is at the heart of all our huge and powerful EIRP systems. We stack the 1kW amplifiers up like Lego bricks and they operate day in, day out 24/7 without batting an eyelid. Strong and robust is an understatement to the physical construction and RF performance of these amplifiers. 1kW is a typical power level for signal penetration of buildings in densely constructed cities
1 Watt Drive (can be more on request!)
Our amplifiers have a uniform input requirement of 1W. In other words, when driven with 1W of power, this amplifier is capable of producing 1000W of RF output continuously, while still adhering to global technical regulations.
If you require a different input power level, no problem, we can do that easily. Just email or message us in the box below for more details.
Temperature Resilience
The first version of this unit was designed for use in the middle of East Africa, so we had to make it good, in fact not just good, amazingly good. We didn't disappoint our client, it was installed 5 years ago and is still fully operational, running day in and day out in the heat of Africa. If the ambient goes beyond 40C, the internal temperature protection starts to back off the RF power, gently, not any abrupt cut out, just a little to keep the internal temperature below 70C.
VSWR Resilience
The final output section of this model uses a BLF188XR, they say the XR means 'eXtremely Rugged' This LDMOS RF power transistor is designed for the toughest engineering environments and is capable of withstanding a severe load mismatch with VSWR greater than 65:1 at 5 dB of compression. The BLF188XR is actually capable of providing an outstanding 1600 W of peak output power and still pass extreme ruggedness testing. For ultra reliability we just run it at 1kW maximum. It can be set at lower power levels, right down to 10W if required.
High Stability
Regardless of high temperature, high VSWR poor antenna and mismatch conditions or poor AC power, the power level of 1000W will remain stable all the time and the RF signal will never pollute the spectrum with instabilities. The output amplifier in this unit is designed to work in hostile conditions and environments. The BBC, British Army and US Army Delta Company all purchased these units for use in Iraq and Afghanistan.
Global Voltage Compatibility
The AC version of this product is genuinely universal and can be used with any AC outlet worldwide, supporting a voltage range of 90 to 260V at a frequency of either 50 or 60Hz.
Antennas
The model will work with our 50 ohm antennas listed below:
Vertical 5/8 Wave
4 Way Stacked Dipole
8 Way Stacked Dipole
Circular Dipole
Folded Dipole
