8dBm amplifier manual

This power amplifier is designed for 2.4G R/C model radio which can help large increase the effective range, features 8dBm gain and come along with e-switch function, no need to connect with mechanic switch and will not consume any power after radio turn off, very simple to operate, using high frequency PCB to decrease the interference and depletion.

The normal RC model radio transmitting power is about 14dBm , after using this amplifier the transmitting power could reach to 22dBm-26dBm(150-500mW),We have already tuned the transmitting power to a perfect value, higher transmitting power will interfere the 5.8 g receiver to work while lower transmitting power will lead to a short distance

Wiring diagram：

Red wire：wire to Battery Vcc，wiring to the pad which features have battery voltage when radio turn off （suitable measure via multimeter，normally beside the battery plug，also can be wired to positive pole of battery balance head）Black wire：wire to GND of the PCB, (measuring via multimeter , also can be wired to negative pole of battery balance head )

Yellow wire ： trigger switch，wiring to the pad which features no voltage when radio off and have voltage when radio on.(Voltage >1V, measuring via multimeter )
