MODEL 4116-T21-310212 Translator, Weather Resistant
*
1.0 General
1.1 Equipment Description
The 4116-T21-310212 Translator converts a 29.0 - 30.0 GHz input RF band to 19.2 - 20.2 GHz or a 30.0 - 31.0
GHz input RF band to 20.2 - 21.2 GHz. Front panel LEDs provide indication of DC Power, and PLL Alarm.
The RF to RF gain is +23 dB, maximum. Connectors are 2.92 mm female for the RF out, RF in and SMA
female for the external reference input and reference output. Gain, band select, and internal 10 MHz frequency
are controlled by the Ethernet M&C or via the Status/Control connector. In AUTO, the 10 MHz reference stays
in external if the external level is in the +2 to +8 dBm range. It is powered by a 100-240 ±10% VAC power
supply, and mounted in a 8” W X 6” H X 16” D Weather Resistant* enclosure.
(NOTE: *Weather Resistant enclosures are designed to be water resistant for installation in an outdoor enclosure/antenna hut OR
mounted outdoors on an antenna assembly at their specified temperature ranges. They are designed to be located “out in the elements”
(water, sleet, snow, etc.) but they are not designed to be “submerged under” water. If an extended temperature range is required, there
is an Extended Temperature option (Option W21; -30˚C to +60˚C) available at an additional cost. Contact Cross for quote.
