30 watts is that level of power where it's not really small, but not really big either, it's about the right size for a village or small. Also useful for mobile operation where you need to run on a vehicle battery for some huge event that covers few miles. Available as a 2U 19 inch rack version shown above or as a compact version shown below.
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 30W 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 Ampleon LDMOS BLP5LA55S RF transistor at the heart of this unit rates it at 66% efficiency in class AB. We don't bias this LDMOS, we run it in class achieving at least 66% or more. Given this it does run quite cool, if you touch the aluminum heatsink fins at the back, they're hot, but not really hot, you can hold you fingers there indefinitely without discomfort. The unit does have a small and quiet 40mm fan just to help it move the air though the heatsink fins.
VSWR Resilience
Again due to the modern Ampleon LDMOS BLP5LA55S our amplifier is capable of withstanding a load mismatch VSWR of 65:1 through all phases. This is the manufacturers rating at an RF output of 55 watts. Since we only use the transistor at just over 30 watts, then it's well within any margin of error and is super robust regardless of the reflected power.
Super Silent ADDED Option
What is SUPER SILENT? it means it's as quiet as a mouse and can use it in a live mic studio without background noise. The video demonstrates the 100 watt transmitter, but it is exactly the same for the 30 and 50 watt units.
If you want SUPER SILENT option, MAKE SURE YOU ADD IT AS AN OPTION in the price panel below.
SUPER SILENT means less 20dBA, this is comparable to a low level whisper in a studio, the chances are other equipment, air con or studio ventilation is higher in volume.
High Stability
Regardless of high temperature, high VSWR poor antenna and mismatch conditions or poor AC power, the power level of 30W 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
This product's AC version is truly versatile and can be used with any AC outlet globally, accommodating a voltage range between 90 to 260V and at 50 or 60Hz.
12V and 48V DC Option
The regular version of this unit is 90 to 260V AC. However we can also manufacture it for 12V or 48V DC. To the best of our knowledge, in the entire world, Only We Make 12V DC FM Broadcasting Transmitters and Amplifiers up to RF Power Outputs of 250W.
Applications include mobile setups where only a car or vehicle battery is available. We have a perfect Magnetic Mount FM Antenna for mobile setups. Also fixed installations with connection to solar battery systems of 12V and 48V DC
We default ship the AC version. If you want the 12 or 48V DC version, it's important you notify us by email when you make your order.
