25W UHF power amplifier car radio amplifier transceiver automatically converted

Description

25W UHF power amplifier car radio amplifier transceiver automatically converted
Note
:  this version just for analog signal
Frequency range: U section covering the entire frequency 400MHz-470MHz
Transmitting power: 25 watts maximum, when 2W input and output 19-20 watts, while the input and output of 5W maximum!
Receive loss: better than 1dB, this value affect the receiver sensitivity can be ignored.
Power supply: 12-14V, supply voltage, the greater the transmit power, 25 watts is 13.8V measured!
Supply Current: launch 3A, does not consume any current reception
Suitable models: a variety of hand-sets and U U segment segment segment operating mode UV double hand Taichung (eg TG-UV2).
Hand Taiwan Power: transmit power for a variety of hand sets in 2-10 watts
Dimensions: 11.5 cm * 8 cm * 5 cm (L * W * H)
Product Features:
This product is a fully automatic internal transceiver integrated circuit and a switching power amplifier, to increase the transmission power walkie-talkies, and the receiving antenna using the machine straight manner, receiving only a loss of less than 1dB, this loss can be ignored, does not affect the receiving sensitivity. (Hand sets factory sensitivity has been commissioning the machine can achieve optimum sensitivity, and generally without additional amplification, but if you increase the amplification receiver dynamic range compression may also cause sensitivity variation, so the industry did not receive the amplified hand power amplifier! !!)
Common transmit power 2W machine reaches after amplification 19-20W, common transmission power 5W machine after amplification reaches 25W. Make your hand sets immediately into "wagon"
Especially for car lovers to use the car as the car received a hand-platform station uses the power amplifier, holding the hand sets off to use, convenient and flexible, do not buy a car sets high cost, but also to take the license test machine review! ! ! Into the family home is OK! Corresponding power supply Taobao home very much, hundreds of dollars on the line!
Baby features a power switch is omitted, up to several watts of RF signals emitted only when the input power to open the power amplifier, except there is no other way to get the power to start. When receiving automatic disconnect the power amplifier, no power when received. This allows you to never have to care about whether the power has been manually shut down other tedious problems. When launching a red emission and power indicator lights will light when receiving the light goes out.
Usage:
1 Please use with this machine comes with RF cable SMA female (gold thread small female) received a hand on the amplifier base station antenna (receiving station where hand tighten the antenna)! That is the figure the small joints received a golden hand sets.
2 Place your seedling receiving antenna or stick a big needle M Mother amplifier head, which is a big needle M amp female connector twist on your antenna! Antennas are generally brought on a feeder, the feeder is thicker the better, the shorter the better! Signal attenuation is too small too big!
The red line on the positive three hosts connected to the power amplifier, the black wire to the negative power supply. If the car comes with a cigarette lighter with our connectors can be directly connected to the cigarette lighter, if the family owned power use to pick up. Stable output power requirements than current 3A output current when the power supply output voltage can not be reduced too much! ! !
After the above steps, you can press the start button to begin transmitting station PPT fired, it is easy, not complicated, we can operate
NOTE:
1 the power cord ban against, anti will burn, red to the anode, black connect the cathode
2 To connect good the antenna when transmitting, is prohibited without antenna launch, it will affect the power amplifier device life or burning device!!!!!
include:
1pc amplifier Host
1pc SMA male to male cable connector 0.5 m
1pc SMA female-female adapter machine
1pc Cigarette lighter adapter (car cigarette lighter for access)
