The FMT5.0-350H adopts an integrated design combining exciter, power amplifier, output filter, and switching power supply into a 2U 19-inch rack-mount case. The humanized digital LCD touch panel displays all system parameters — frequency, mode, volume, amplifier temperature, audio UV meter, forward/reflected power, modulation mode, and pre-emphasis — with direct touch control for an intuitive operating experience.
The RF amplifier uses LDMOS transistors capable of withstanding severe load mismatch exceeding 65:1 VSWR at the 5dB compression point. Nine latest device alarms are automatically logged for easy troubleshooting. Supports external RDS/SCA signal input and AES-EBU digital audio up to 24Bit/192kHz. Power output is continuously adjustable from 0 to 350W via AGC balance control.
The humanized digital LCD touch panel displays all system parameters: transmitter frequency, stereo/mono mode, volume, amplifier temperature, audio signal UV meter, forward power, reflected power, modulation mode and pre-emphasis settings. The integrated LCD provides direct touch control for a simple operation experience.
The RF amplifier uses LDMOS transistors capable of withstanding severe load mismatch exceeding 65:1 VSWR at 5dB compression point. The transmitter automatically records 9 latest device alarms for easy troubleshooting. Supports external RDS/SCA signal input and AES-EBU digital audio with 24Bit/192kHz true lossless quality.
