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.
Should you need a different input power level, there is no issue, as we can readily accommodate your request. Simply send us an email or message us using the box below.
Temperature Resilience
The power output of this model is 1kW continuous day and night non stop 24/7. It has reflected power protection and it has over temperature protection. In the event of any of these protections being activated, the power will reduce to a safe level to prevent any damage. When the fault that triggered the protections clears, the power restores automatically back to full.
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
All our transmitters and amplifiers remain stable in power and spectrum purity regardless of VSWR mismatch, over temperature, incorrect supply voltages etc. They will work in hostile climates and still remain within the International Telecommunications Union (ITU) standards at all times.
Global Voltage Compatibility
All AC version of this product is truly globally compatible, you can plug it into any AC outlet in the world from 90 to 260V at 50 or 60Hz
The model will work with our 50 ohm antennas listed below:
Vertical 5/8 Wave This amplifier complies with EMC, Voltage Safety and RTTE Harmonised Standards laid down by the European Union. It's CE marked with a Declaration of Conformity.
