3. Major Parameters
Smart Amplifier fitted with a Low Noise amplifier (LNA) and together with its
unique bi-directional features is fully capable of enhancing the coverage area of
2.4 GHz radio signals by amplifying transmitted and received signals.
The Smart Amp ensures a seamless RF link in most installations with long cable
losses. Its unique outdoor design enables it to be mast mounted and to operate
in wide temperature range of –40 to +75 C.
2.5 mW (+4 dBm) input to the amplifier delivers 1Watt output. For signal
input values greater than 4 dBm the Smart Amplifier attenuates the signal
accordingly and keeps the output at 30 dBm. Up to 200 mW of power may
be safely applied directly to the amplifier input without causing any
damage.
The complete set includes:
1. An outdoor unit, the SmartAmp
2. DC injector
3. Universal power supply
4. Mounting hardware.
The DC injector carries the power along with RF signal to the outdoor unit via co-
axial cable.
