MODEL 2115-122 Block Upconverter
1.0 General
1.1 Equipment Description
The 2115-122 Block Upconverter converts 0.95 - 1.45 GHz to 12.2 - 12.7 GHz with low phase noise and flat
frequency response. Frequency translation is via a 11.25 GHz local oscillator. Front panel LEDs provide
indication of DC Power, External 10 MHz, and PLL Alarm. The gain is +20 dB. Connectors are SMA female
for the RF and BNC female for the L-Band and external reference input and reference output. A three-way
switch controls which 10 MHz reference is being used. In the INT position, the internal reference is used, in
the EXT position, the external reference is used, and in the AUTO position, the internal reference is used unless
a 3 dBm ± 3 dB, 10MHz reference signal is connected to the external reference input. The 2115 is powered by
a 100-240 ± 10% VAC power supply, and mounted in a 1 3/4” X 19 “ X 14” rack mount chassis.
