Introduction
The UMC16B multi-coupler is used to distribute the
signals from two antennas to eight diversity receivers to minimize the amount of cabling and antennas
needed in multi-channel wireless systems. The design
combines broad band ceramic filtering with low noise,
high intercept point RF distribution to provide outstanding performance and flexibility. Up to eight diversity
receivers or up to 16 non-diversity receivers can be
utilized across a 230 MHz passband.
Various models are available, covering different frequency bands in the UHF spectrum.
The UMC16B can be powered from an external supply,
10 to 18 VDC for mobile applications, or from 100 to
240 VAC for installations using the regulated power
supply furnished with the unit. A locking connector on
the rear panel secures the power connection.
UHF Antenna Multicoupler
The RF signals at the inputs first pass through a
ceramic filter to block energy above and below the
passband. The signal is then fed to a high current
amplifier to apply the gain needed ahead of the splitter.
The amplifier is a high current type with a very high
IP3 (third order intercept) that minimizes intermodulation products.
The amplifier output is then distributed to the output
jacks using a Wilkinson “strip line” RF splitter. Unused
outputs should be terminated with 50 Ohm dummy
loads for maximum performance, however, the splitter
design allows unused jacks to remain un-terminated
with only a slight effect on other channels (+/- 1 to 2
dB in the level at the outputs).
The unit is housed in a standard 19 inch rack mount
assembly with rugged connectors.
