System Description
Antenna
Applications
The UltraSpan™ antenna/amplifier system extends the operating range of broad-
band wireless systems operating in the 2400-2500 MHz spread spectrum band.
The basic unit consists of a MICROCEPTOR
®
antenna and a built-in bi-directional
amplifier operating in Time-Division Duplex (TDD) mode. It features intelligent
algorithm and Automatic Gain Controlled (AGC) circuits which maintain transmit
power and prevent transmit signal saturation, thus minimizing signal distortion.
The system also includes a universal power supply, a DC power inserter, and
mounting hardware.
The UltraSpan system has applications in a wide range of wireless systems
where TDD technology is used, such as Wireless Local Area Network (WLAN),
Wireless Local Loop (WLL), Wireless Internet Access (WIA), and wireless modem
connection with point-to-point systems.
MICROCEPTOR Antennas are small, aesthetically pleasing antennas for broad-
band applications. They feature a patented feed design for excellent directivity in
a low profile package.
This key feature automatically detects the power level and adjusts the amplifier
gain to allow for system variables. For example, the AGC adjusts for different
interconnecting cable lengths and radio modems with different output powers.
The AGC Transmit Amplifier is fully operational in a wide transmit input power
range of 1 to 200 mW. An input signal of 2.5 mW delivers the maximum U.S.
FCC specified power level. The AGC attenuates input signals greater than 4 dBm
and maintains a maximum output power of 26.2 dBm.
The amplifier is built into the back of the MICROCEPTOR antenna and is
encased in a weatherproof enclosure. It features a low noise amplifier and an RF
filter that decreases potential RF interference and overload caused by out-of-
band frequencies, such as those received from higher power wireless communi-
cation systems.
