WISTEC amplifier is designed specially for use with 2.4 GHz Direct
Sequence and Frequency Hopping Spread Spectrum radio products. It's
the highest performance wireless LAN amplifier available today.
This waterproof bi-directional
pole mounted amplifier greatly increases operating range by compensating
for various cable losses, increases receive range by extremely low
own noise level (2.8db) and very high sensitivity, increases transmit
range because the high output lever.
AGC (automatic gain control) circuit automatically adjusts the amplifier's
gain to provide a constant output/input power in both transmit/receive
modes regardless of cable length or type.
The very important parameter
determined with 802.11 standard is a level of non-linear distortions
(main/side lobe) which in its turn depend greatly on the temperature.
The depth of the regulation of AGC of WISTEC amplifier is so effective
that allows to keep the signal level deviation within +/- 0.5dB
while a temperature range is -50…+50C.
The ratio main/side lobe is also within the limits allowed by the
802.11 standard.
WISTEC amplifier is powered through the antenna transmission cable
using the DC Power Injector, which is located indoor near the radio
modem, simplifying installation. Current-sensing circuits provide
reliable remote amplifier diagnostics via two indicator LEDs.
Features:
- Allows wireless station to work with a great separation between
indoor radio and outdoor antenna;
- Automatic transmit/receive gain control;
- Built-in filter allowing co-location with different RF systems;
- Weatherproof Cast Aluminum Case with UV-stable finish;
- Great temperature operational range;
- Atmosphere electricity and lighting protector;
- Powered over the single RF cable;
- Power and Transmit LED indicators on DC Injector;
- Mountable on pole/wall;
- 2 Year warranty.
