0-600W radio broadcast station FM transmitter PCB KITS


1、 It applies the most advanced LDMOS transistor MRFE6VP5600H on the new amplifier, makes which posses a higher VSWR that can reaches 65:1. In the same time, it still can resists 28 db gain and 80% efficiency. The good performance has greatly exceed BLF574

2、 The architecture proposal which we raised for FSN-600 is efficient with lower budget by using the PCB material is Teflon. It is composed by LPF and power detector coupler. Meanwhile, the FME-1B interface is compatible. And the installation is more simpler and faster when combined with FME-1B. The reason why we do this is to lower down the threshold of the installation for the 600w transmitter equipment. Even a new member only need no more than half an hour;

3、 Although we did not provide the free service guarantee for the previous production, we change the rule since we sell the production of FSN-301. If you buy any of the two transmitter , you can enjoy the two years free after sale guarantee for LDMOS , and one years for all the hardware. which is never happened before.

How far(long) the transmitter cover?

The transmission range depends on many factors. The true distance is based on the antenna installing height , antenna gain, using environment like building and other obstructions , sensitivity of the receiver, antenna of the receiver . Installing antenna more high and using in the countryside , the distance will much more far.

EXAMPLE 5W FM Transmitter use in the city and hometown:

I have a USA customer use 5W fm transmitter with GP antenna in his hometown ,and he test it with a car, it cover 10km(6.21mile).

I test the 5W fm transmitter with GP antenna in my hometown ,it cover about 2km(1.24mile).

I test the 5W fm transmitter with GP antenna in Guangzhou city ,it cover about only 300meter(984ft).

Below are the approximate range of different power FM Transmitters. ( The range is diameter )

0.1W ~ 5W FM Transmitter :100M ~1KM

5W ~15W FM Ttransmitter : 1KM ~ 3KM

15W ~ 80W FM Transmitter : 3KM ~10KM

80W ~500W FM Transmitter : 10KM ~30KM

500W ~1000W FM Transmitter : 30KM ~ 50KM

1KW ~ 2KW FM Transmitter : 50KM ~100KM

2KW ~5KW FM Transmitter : 100KM ~150KM

5KW ~10KW FM Transmitter : 150KM ~200KM
