Product Description

1. Product overview

With rapid development of communication networks, communication has brought a lot of convenience and fun to our work and life. However, sometime we can not make a call normally . The vehicles signal amplifier would help us effectively resolve this issue.

The vehicles signal amplifiers enable us to maintain a normal phone call in the high-speed driving. It strengthen the signal in the car, at the same time ensure that our mobile internet speed. It can be effective to reduce cell phone radiation, so that conducive to our physical health.

2. Principle

The vehicle receive the weak BTS signal by donor antenna, and proceed to the linear amplifier, and sent the strong signal to phone by service antenna. At the same time Vehicle amplifier receive MS signal by service antenna, amplify it , transmitter it to BTS by donor antenna

It can effectively eliminate car coverage blind spots and interference suppression. It provides stable and reliable signals for users. Users can also enjoy high-quality personal communication services in high-speeding driving cars.

3. Features

² A low-noise amplifier circuit design, particularly small noise figure.

² High linearity, low Inter-modulation, and inhibit the band-band interference.

² The system ALC is double redundancy, Prevent accidents.

² Stable and reliable design of the electromagnetic compatibility, not to interfere with other equipment.

² No interference from the base station, and did not to adjust parameters after the opening of the original system.

² After the system is power up, the input power is detected automatically and then the output power is adjusted. After the downlink gain is calculated by the system, the uplink gain can be adjustment equivalently.

² Convenient installation and commissioning, users can install itself without professional staff and equipment.

² It has the function of oscillation automatically detection between the donor antenna and service antenna.

² Low power consumption.

² Small size, light weight, good looks.
