Introduction
FMT5.0-150H FM radio transmitter is highly reliable, lighter in
weight and easier to operate than previous version of transmitter.
This transmitter adopts a simple-style design concept. It
integrates the 150W FM stereo transmitter exciter, power amplifier,
output filter and switching power supply in a 1U high 19-inch
standard case, reducing the connecting cables between the
components.
Technical Features:
• User-friendly digital LCD panel, using one rotary knob to
control.
• The integrated LCD screen displays all the parametric including:
transmitter frequency, stereo and mono, volume, amplifier tube
temperature, audio signal UV meter, forward power, reflected power,
modulation mode, pre-emphasis etc,.
• 1U 19-inch thickened all-aluminium case, strong and excellent
heat dissipation.
• Precise PLL frequency generation system, to ensure that the
frequency not drift away for more than10 years, with built-in
high-quality stereo encoder.
• Outstanding power AGC balance control system, adjustable power
output from 0 to 150 watts, and automatic gain power control to
maintain output power within set range without drifting.
• Signal input supports XLR and RCA audio inputs, and also SCA and
RDS signals using the BNC connector AUX.
• The RF amplifier uses LDMOS transistors to withstand even severe
load mismatch exceeding the 65: 1 VSWR at a 5dB compression point.
