600W FM radio transmitter used in broadcasting, television, radio communication

 

Introduction:

 

This transmitter adopts the concept of simple design and integrates the ex citer and power amplifier, output filter, switching power supply, etc into a 2 U high 19-inch standard case. This advanced design reduces the number of connection cables and improves the overall efficiency of the transmitter, ma king it more reliable and easier to operate.

Features

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

l 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.

l 2U 19-inch thick aluminum alloy case, which is not only sturdy but also has good heat dissipation.

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

l 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.

l Support external input modulation RDS or SCA signal.

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

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

 

l RF amplifier uses  LDMOS transistor BLF188XR, making it able to withstand severe load mismatch of more than 65: 1 VSWR at 5dB compression point.

l Automatically record 9 latest device alarms for later troubleshooting.
