433MHz FSK digital radio / input amplifier 19dBm Output 3 - 5W half duplex The amplifier can increase the transmission distance FSK communication system , when used with the need to provide pre- FSK transceiver logic board two IO ports to control this amplifier transceiver switch. 19dBm input power of 3W RF power can be output. FSK systems greatly increase the transmission power , thereby increasing the coverage. 2 Product Index Enter 19dBm Output 3W / supply 7V Output 5W / Power 9V Emission current 0.75A Working frequency 433MHZ Receive current 0mA receive does not consume electricity Receive loss 0.7dB Properly connected according to the connection method above, When launch timeWith pre- boardCPUControlTRLogic10, Then the amplifier in the transmitter, the signal over the pre- launch after launch amplifier power amplifier to the antenna into the air .When receiving timeWith pre- boardCPUControlTRLogic01, Then the amplifier in the receiving state, the receiver down on the antenna signal amplifier to the RF chip in after receiving demodulation!
