FMT5.0-5000H 4U  Series FM Broadcast Transmitter Technical Parameters


   This transmitter adopts the concept of simple design. The 5000w  transmitter integrate the exciter and power amplifier, output filter, switching power supply, etc into a 4U high 19-inch standard case. This advanced design reduces the number of connection cables and improves the overall efficiency of the transmitter, making it more reliable and easier to operate.


- Humanized digital LCD touch panel, simple operation interface with direct touch control.

- The integrated LCD displays all system parameters: transmitter frequency, stereo and mono, volume, amplifier tube temperature, audio signal UV meter, forward power, reflected power, modulation mode, and pre-emphasis etc.

- 4U 19-inch thick aluminum alloy case, which is not only sturdy but also has good heat dissipation.

- Precise PLL frequency generation system to ensure the frequency does not drift within at least 10 years.

- Built-in high-quality professional stereo encoder.

- Excellent power AGC balance control system, the power output can be adjusted from 0 to full power, and has automatic gain power control to maintain the output power within a set range without drifting.

- Support external input modulation RDS or SCA signal.

- Supports AES-EBU digital signal input, 24Bit 192KHz sampling rate input range, true lossless audio.

- Equipped with RS232 communication interface, users can control all operations through the transmitter communication protocol.

- The RF power amplifier part is synthesized by using multiple modules, and the amplification module uses NXP LDMOS transistor BLF188XR. It is able to withstand severe load mismatch of more than 65: 1 VSWR at 5dB compression point.

- All circuits adopt the design of split modules, and each modules have status indicators to check its working performance, which reduces maintenance and replacement costs.

- Innovative RF module status monitoring and fault notification. If a module fails, you only need to replace the  module with specified number according to the system prompt.

- Automatically record 9 latest device alarms for later troubleshooting.
