Interference to your 3G and 4G services?

Comments Off on Interference to your 3G and 4G services?


newBetter Data with our New Bandstop Filter

With more and more of our clients having problems with LTE and 3G interference from different RF sources, this new filter helps prevent any interference from the frequency band 1983.1 – 1990 MHz.

Interference Prevention with Customisation

We can customise any Passband and Stopband for your case with 30 to 50 dB rejection suiting your needs. Normally 30dB rejection is adequate in most cases, meaning that the interference is supressed to at least 20 times lower in power. This will improve voice and data significantly, bring more traffic, more revenue and happier customers in the network with improved LOYALTY!

Comments Off on Variable Power Management for LTE

LTE 4G variable attenuator

When it comes to precise control of power levels, DragonTECH has the best LTE solutions.

Systems like optical RF transport systems require flexibility for the site enginer to be able to finetune power levels, and yet high precision is required. Not to mention that it needs to be very reliable so the power levels stay exactly the same after testing and commissioning.

Consider the Variable Attenuator LTE 0-3000MHz, contact us for more details.

Comments Off on I bet you will never forget to bring that Jumper Cable along

3 way splitter with JumperWe will give you Spliiters with Jumper Cables Affixed!

We have a new series of Power Dividers that comes with the necessary Jumper Cables. The length and connectors can be customised.

This alleviates a lot of connections on site for a faster and easier implementation. In cases where clients are charged according to the BoQ this new idea greatly reduceds install cost.

We can customise Jumper Cables and RF components for you.

Check it out on our Products page.
