Outdoor RF Amplifier
Suitably used in bi-directional transmission (can be reserved) and signal equalization of multi-class trunk transmission or high-required distributive network. Adopt PHILIPS, NEC imported power doubler modules. Audio pre-amplifier is low-noise microwave tube push-pull amplifier to insure enough gain. It has 1 input and 2 outputs, and each connection has over-current protection. The output branch or distributiveness can be changed following it. Double-equalizer is used, so adjusting multi-class transmission flatness is simple and convenient. Attenuator and equalizer are plug-in, so customers can choose fixed or adjustable style. High-reliable switch power (or linear power) and strict waterproof and anti-thunder design insure steady durative work.
Key Features of Outdoor RF Amplifier
1. Signal amplification: increase the power of the received RF signal and improve the signal quality.
2. Noise suppression: reduce the noise in the signal and improve the signal-to-noise ratio.
3. Extended Coverage: Extend the coverage of wireless communication systems by enhancing signal strength.
4. Adjustable Gain: Users can adjust the gain of the amplifier according to their actual needs to achieve the best performance.
5. Two-way transmission: It supports the amplification of both uplink and downlink signals, and is suitable for two-way communication systems.
