MODEL 4115-300 Ka-Band Upconverter, Weather Resistant*
1.0 General
1.1 Equipment Description
The 4115-300 Ka-band Block Upconverter converts 0.95 - 1.95 GHz up to 27.5 - 31.0 GHz in four selectable
fixed bands. Front panel LEDs provide indication of DC Power and PLL Alarms. The L-band to RF gain is +30
dB. Connectors are 2.92.mm for RF Out and RF Monitor, SMA for the external reference input and reference
output and Type N (all female) for the L-band. Gain, band select, and internal 10 MHz frequency are controlled
by the Ethernet M&C. 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”Wide X 6”High X
16”Deep 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
