Where to buy FM Transmitter? Guide from TEKO BROADCAST


TEKO produces a complete range of products capable of satisfying the demands of every type of broadcaster.

In this guide, we will shows where the best way to choose a transmitter and where is possible to buy it in your country

The following guide describes the specifications to consider before purchasing and shows where to buy in your country or region. Let’s discuss some of the features that we found to be most important when searching for the best FM transmitters for your you Radio:

  • Frequency Range: It depends on your country, typically will be in the range of 87,5-108MHz but in some countries, Russia or Japan there are different standards like OIRT ecc.
  • Broad Compatibility: you need an FM transmitter that can easily be installed on your Site, Output connector, input mains connection, Audio inputs, Rack Mount are some aspects to take in count.
  • Sound Quality: the key to an enjoyable listening experience is good sound quality. This is why we considered FM transmitters that were able to transmit sound clearly and to cut down on any kind of distortion as well.
  • Usability: since you will be using and giving maintenance to the  FM transmitters for many years, it is imperative that they are simple to use and to maintain, even if you are alone on the Radio Station Site and need to transport by your self some spare parts or the complete Transmitter.
  • Architecture:The FM Transmitter can be Compact, Semi Compact or Modular, in the Modular type the several stages RF amplifiers are combined. In this case, the type of combiner used must be take in count.

2kW to  80kW FM Transmitter Series Standard and HOT PLUG-IN versions

The CORTEX SMP© Superior Modular Philosophy is a family based on a very compact Amplifier Module.

It combines form 2 to 10 Low Power RF amplifiers to create a High Power FM Broadcast Transmitter.

Thanks of the size, 2 HE, power levels 2,2 kW, it is the more redundant Modular FM Transmitter of the market.

The CELL RF Amplifier has 2,2kW output power with High Efficiency Planar LDMOS Technology.

The modular architecture is completed with:

  • High Efficiency Solid State FM Amplifiers 
  • Special combiners
  • FM exciters and control logics
  • the FM exciter can be Analogue or DDS
  • both with integrated AES/EBU interface.
  • FM Stereo Transmitter/Exciter
  • Has built in Stereo Generator

SMP unique TEKO Radio Equipment Architecture is every modular and able to grow in power (scalar) and the robustness.

SMP, based on combine low power amplifiers, gives the maximum output power in case of fault of one amplifier.

SMP is the Radio Station Equipment more Robust of the broadcast chain.

To better understand the benefits of it’s philosophy, let us explain how it works a Radio FM Broadcast System.

How an FM Radio Broadcast System is composed.

I’s composed by many parts like:

  • Transmitter
  • Antenna
  • Radio Links
  • the Mains Electric Supply


…..but everybody agrees the king is the FM Transmitter.

FM Transmitter Structure

It is mainly composed of two parts:

  • The FM Exciter, even known as FM Modulator.
  • The output RF Amplifier.

When it’s necessary to have High Power Transmitters this are obtained by combining two or more RF Amplifiers.

  • So, the complete FM Transmitter chain is build as follows:
  • Starting by an FM Exciter and then..
  • This low power FM Signal is amplified by several RF Amplifiers and then...
  • This combination creates a Low, Medium or High Power FM Transmission system.
  • RF Amplifier

The LDMOS, the heart of any RF amplifier, is the active component that produce the amplification.

The LDMOS amplifiers the Low Output Power FM Exciter, to the high Power at the output of the Transmitter.

The LDMOS has the ability to handle high RF Power levels with a big capacity of Heat Dissipation.

On FM Radio application the maximum power handle by the LDMOS with the modern technology about 1kW or 1,5kW.

To reach higher power levels is necessary to combine them in to reach higher power levels.

The most common LDMOS devices used on the Broadcast Industry at the moment are:

  • BLF188.
  • BLF189. MRF1K25. MRF1K5
  • and MRF1K8.

The strategy used by the Producers is to combine a number LDMOS in a single Medium Power RF Amplifier.

The RF Amplifiers output power in a range between 1kW and 6kW.

The amplifier is obtained by the combination of a variable number (between 2 and 6) LDMOS devices.

With this number of LDMOS it’s obtained output powers between 2 and 6 kilowatts.

High Power FM Transmitter

It’s built combining two or more Medium Power RF.

A High Power FM transmitter is obtained by the combination of a variable number, between 2 and 10.

To do this, the constructors choose between four philosophies:

  • Use only one high power FM Amplifier Module.
  • Combine High Power Amplifiers Modules.
  • Combine Low Power Amplifiers Modules “only RF” type, it means, an RF Module without Power Supply, Fans and Control Logic.
  • Combine Low Power Stand Alone Amplifiers Modules (this is the option adopted on CORTEX).




They are few essential things, the transmitter must be:

  • Always on Air: this is the main thing, nothing is more important, It must me reliable.
  • Easy maintenance.
  • Easy to transport and handle by one person, it avoids the needing to go two or more technicians to make maintenance
  • the optimal wight  is modules with less than 15 kg (35 lbs) weight,
  • Low Energy consumption.

CORTEX SMP© Superior Modular Philosophy

To full meet the Broadcaster needs, we create a modular structure with an RF Amplifier Module, obsessively optimized for best results.

Big broadcast systems benefits of this optimization.

SMP Superior Modular Philosophy is the synthesis of robustness easy maintenance and low energy consumption.
