Multicouplers
High-dynamic low-noise
antenna amplifiers, receiver antenna multicouplers, antenna selectors, antenna
signal routing
matrixes
The wideband active antenna multicoupler is used in radio communications and wideband receiving systems to connect several receivers to a single antenna in such a way that the equipment impedance is properly matched to the antenna impedance, with no loss of signal power. In fact, often gain is introduced by the multicoupler to overcome the noise figures of following stages. Multicouplers are key components in signal routing and distribution systems such as the full fan-out antenna signal routing matrix. Key indicators of the quality of an antenna multi-coupler are the following points.
Low multi-coupler noise figure
High dynamic Range
Low inter-modulation distortion
High port-to-port isolation
High level signal protection
Band pass filtering (optional)
SDU-500 Receiver antenna multicoupler
Features
Multiband operation
Very high intercept points
Good noise figure
Compact units for rack mount
8 or 16 port versions
Product description
The unit is a high performance state of the art
receiver multicoupler based on advanced high-dynamic range signal routing and
antenna amplifier technology. It could be used as antenna multicoupler or
distributing any
kind of signals in measurement or receiving systems in its operation range with
high-dynamic range and low-distortion. This receiver multicoupler unit reflect Sagax's
ability to design and produce multiband antenna systems for serach, intercept,
monitor and collection receivers with multiband frequency coverage.
Typical applications
Spectrum monitoring and management
Search intercept scanner receivers
Monitoring and collection receivers
Multiband intercepting and monitoring receivers
Signal intelligence (ELINT, SIGINT, COMINT) and surveillance systems
Typical performance
Insertion loss of the HF/VHF receiver multicoupler
