25W 400MHz-470MHz UHF Radio Analog Power Amplifier Transceiver 12V

Description

25W 400MHz-470MHz UHF Radio Analog Power Amplifier Transceiver 12V
Features：
This product integrates the automatic transmission and reception switching circuit and power amplifier to increase the transmission power of the intercom. For the receiver to use the antenna to pass through, the reception only has less than 1dB loss. This loss can be neglected and has no effect on the receiving sensitivity. (The factory sensitivity has been debugged to the best sensitivity that can be achieved by the machine. Generally, there is no need to add additional amplification. If the amplification is increased, the dynamic range of the receiver may be compressed, which may cause the sensitivity to deteriorate. Therefore, the industry does not have a hand amplifier for receiving amplification! !!)
The ordinary 2W transmitting power machine is amplified to reach 19-20W, and the ordinary 5W transmitting power machine is amplified to 25W. Make your hand platform immediately become a "carriage"
It is especially suitable for the riders to use. It is used as a car on the hand-held platform. It is convenient and flexible to use the hand-held platform. It is not necessary to buy a car, and it is necessary to check the license. ! ! It is OK to put it home at home! The corresponding power supply for home is very much on Taobao, dozens of dollars will be fine!
The baby features a power switch that is omitted. Only a few watts of RF signal power input during the launch can turn on the power amplifier. There is no other way to start the power. When receiving, the power amplifier automatically disconnects the power supply and does not consume power when receiving. This allows you to never have to worry about the cumbersome problem of whether the power has been manually turned off. The red emission indication and power light will be on when transmitting, and the indicator will be off when receiving.
