This product is based on integrated systems and the fool mounting purpose, we launch a special of the FME controller with FMA amplifier FM broadcast transmitter solutions quickly. It can include the display of the transmitter, control, PLL, RF amplifier, filters, etc to Integration solutions. it makes Transmitter manufacturers reduce production costs and time. And improve the stability and reliability of the product. So as to reduce the the user productivity transmitter threshold. Users do not need professional equipment can quickly produce FM broadcast transmitter
- FME panel integrated LCD display, MCU control, phase-locked loop, stereo generator, 1W power amplifier and other components.
- FMA amplifier board using a green double-sided high-frequency epoxy PCB, the bottom of the aluminum base plate thermal conductivity. Excellent high-frequency characteristics, aesthetic appearance. FMA amplifier board structure contains the RF amplifier circuit, the low-pass filter circuit, VSWR protection circuit.The RF amplifier produced by the American M / A COM military grade MOS transistor MRF173 constitute. FME control panel input signal 0 ~ 1W, power amplifier, filtered output 0 to 80 watts. And use the power of AGC to maintain the power balance drift
- combine FME and FMA amplifier control panel board ,and LCD Monitor will display transmitter frequency, stereo or mono volume, amplifier tube temperature, the forward power, reflected power, VSWR.
