[FMK-600W]: 0-600W radio broadcast station FM transmitter PCB KITS
FMK-600W,0-600W radio broadcast station FM transmitter PCB KITS $1168
Package: - Amplifier board *1 - Control panel board *1 - Interface board *1 - Connection cable *3


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 FMA-5600H 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 FMA-5600H. 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.
