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.
