FM Analog Audio Broadcast Transmitter – 500W to10kW FM

KT’s 500W, 1kW, 3kW, 5kW, 10kW series FM analog audio broadcasting transmitter based on BLF188 power amplifier tube design and touch screen monitoring.

It consists of an actuator, a monitoring unit (including a switching module), a power distributor, a power amplifier unit, an energy synthesizer, a directional coupler, a low-pass filter, a switching power supply and other unit circuits. Support L/R analog interface or AES/EBU Digital Interface audio signal, after signal processing and level adjustment, after stereo coding, forming MPX composite audio signal, Composite audio signal to 87.5-108mhz frequency of the carrier modulation, output FM radio frequency signal, and then by the pin diode composed of an electric regulator to FM radio frequency signal continuous adjustable, to control the power size of the whole machine. And then through the multistage amplification link output is larger than the rated output power RF signal.
