Product Description

1000W fm transmitter


1000W/T Compact FM Stereo Transmitter



This 1KW FM Transmitter uses new DSP + DDS digital technology for FM radio modulation board. It uses the new generation of high efficiency RF LDMOS transistor; low loss lumped filter; high reliability switching power supply and other components all been installed in a 2U height; 19-inch standard chassis. It reduced connection cables between components in common transmitter, so it’s higher reliability and more easy for operation. The Modular design which form the compact and superior performance of the new 1KW FM radio transmitter. It has unparalleled technical indicators, the audio effects close to CD-quality.

This Transmitter uses modular structure design, it’s easy for maintenance and repairing; it’s using high reliability; wide band switching power supply which is suitable for global power application; the SMT chip can improve the reliability of this Transmitter.




● High performance; high efficiency; high reliability; small size design.

● The entire transmitter be installed in one 2U height; 19 inch; High-quality stainless steel chassis. Compact structure.

● All-digital technology process DSP+DDS, Achieve CD quality perfect sound effect.

● Analog & Digital (AES/EBU) audio signal input directly, Digital can be priority.

● 1KW power amplifier module uses the newest high-efficiency LDMOS transistor (1400W); it’s using microstrip impedance transformation technology; high efficiency & good consistency, easy for maintenance and replacement.

● Power amplifier radiator uses patented technology design, small wind resistance, large cooling area, high thermal conductivity.

● Using long-life German gale axial fan, high air volume, it can ensure long-term stable operation of the Transmitter.

● Power amplifier uses high reliability switching power supply, large amount of redundancy.

● Switching power supply has protection functions of over voltage, over current, under voltage, over temperature, short circuit, phase loss & lightning strike.

● Transmitter has protection functions of VSWR, over power, over temperature, over voltage, over current and lightning strike.

● All technical parameters can be read through the OLED LCD, intuitive and convenient.

● Power control using closed-loop automatic gain control (AGC), it can ensure the stable output power without drift.

● It uses TCP/IP and RS232 remote control interface, it’s easy to managed by local PC and remote monitoring.

    Dear Sir,

    This is Leo from Great billion, Hong Kong. We have a requirement for multiple units of FM transmitters (freq.87.5-108MHz,1KW & 2KW).
    For your reference, please find the link to the type of amplifiers we are after
    Do you supply such transmitters?
    We need accessories such as antennas and cables as well.
    Can you please quote FOB price for the following:
    1. 1kW FM transmitter with two antennas (Omni and directional). The FM transmitter will be installed in a vehicle so the antennas have to be suitably selected
    2. 2kW FM transmitter with two antennas (Omni and directional).
    3. RF cables (10m and 20m) for these transmitters.
    Please send individual prices for all the items above.

    Leo Liao
