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 show you what are the best ways to choose a transmitter and where it is possible to buy one in your own country.

The following guide describes the specifications to consider before purchasing an FM transmitter, and shows you where you can buy in your own country or region.

Let’s discuss, then, some of the features that we found to be most important when searching for the best FM transmitters for your Radio:

  • Frequency Range: It depends on your country, typically it will be in the range of 87,5-108MHz but in some countries, such as Russia or Japan, there are different standards (like OIRT, etc...).
  • Broad Compatibility: you need an FM transmitter that can easily be installed on your Site. Output connectors, input mains connections, Audio inputs, Rack Mounts are some of the aspects to be taken into account.
  • 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 also cut down on any kind of distortion.
  • Usability: since you will be using FM transmitters for many years, it is imperative that they are simple to use and to maintain, even if you are alone in the Radio Station Site and need to transport some spare parts or the complete Transmitter by yourself.
  • Architecture:The FM Transmitter can be Compact, Semi Compact or Modular. In the Modular type, several stages of RF amplifiers are combined. In this case, the type of combiner used must be taken into account too.

  • Low Power FM Transmitters: SYNAPSE, AXON and NEURAL Series
  • Medium Power FM Transmitters: SENSOR Series
  • High Power FM Transmitters: CORTEX Series

The names of the products categorised but their architecture are:

  • Compact Architecture: SYNAPSE, AXON and NEURAL Series
  • Union or Semi Compact: SENSOR Series
  • Modular Combined: CORTEX Series

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 from 2 to 10 Low Power RF amplifiers to create a High Power FM Broadcast Transmitter.

Thanks to its size, 2 HE, power levels of 2,2 kW, it is the most redundant Modular FM Transmitter on the market.

The CELL RF Amplifier has 2,2kW output power with a 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)
  • with integrated AES/EBU interface
  • FM Stereo Transmitter/Exciter
  • a Built-in Stereo Generator

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

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

SMP is the most Robust type of Radio Station Equipment on the broadcast chain.

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

What an FM Radio Broadcast System is composed of.

I’s composed by many parts, such as:

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

…..but everybody agrees the king component 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 is necessary to have High Power Transmitters, these are obtained by combining two or more RF Amplifiers.

So, the complete FM Transmitter chain is built as follows:

  • Starting from an FM Exciter...
  • The low power FM Signal is amplified by several RF Amplifiers and then...
  • This combination creates a Low, Medium or High Power FM Transmission system.

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

The LDMOS amplifies the Low Output Power FM Exciter to the high Power at the output end of the Transmitter.

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

On FM Radio applications the maximum power that can be handled by the LDMOS with modern technology is about 1kW or 1,5kW.

To reach higher power levels it is necessary to combine more amplifiers.

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

  • BLF188, BLF 189
  • MRF1K25, MRF1K5
  • MRF1K8

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

The RF Amplifier's output power is in a range between 1kW and 6kW.

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

With this number of LDMOS an output power between 2 and 6 kilowatt is obtained.

High Power FM Transmitters

They are built by combining two or more Medium Power RF.

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

To do this, the constructors choose between four philosophies:

  • Using only one high power FM Amplifier Module.
  • Combining High Power Amplifier Modules.
  • Combining Low Power Amplifier Modules "RF type only". This means: an RF Module without Power Supply, Fans and Control Logic.
  • Combining Low Power Stand Alone Amplifier Modules (this is the option adopted for CORTEX).


A few essential things... The transmitter must be:

  • Always on Air: this is the main thing, nothing is more important than this: it must be reliable.
  • Easy maintenance.
  • Easy to transport and to be handled by one person. It avoids the need to have two or more technicians to work on it.
  • The optimal weight of the modules is less than 15 kg (35 lbs).
  • Low Energy consumption.

CORTEX SMP© Superior Modular Philosophy

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

Big broadcast systems benefit from this optimization.

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