Transmitter System
The Transmitter converts the broadband signal provided by the digital headend modulators to the transmit microwave frequency (typically in the 2500 to 2586 MHz frequency range) and amplifies the resulting microwave signal to the power level desired for transmission.
Cable AML's MMDS broadband transmitters feature linearization circuits for maximum power with minimum distortion.
The transmitters are usually located near the antennas to minimize signal loss through the transmission lines connecting the two.The Antenna and accessories include the the antenna itself; the cables and waveguide connecting the transmitter to the antenna; and the pressurization system for the antenna, if required.
The radiation pattern of the transmitter antenna (polarization, elevation and azimuth coverage, electrical tilt and gain) have to be selected to match the desired geographical coverage for a given transmitter height and location.
If the transmitter is a distance away from the Headend, Cable AML can provide broadband microwave links to transport the video signals from the Headend to the transmitter.
