MODEL 2116-31T21 Block Translator
1.0 General
1.1 Equipment Description
The 2116-31T21 Block Translator converts 30.0 - 31.0 GHz to 20.2 - 21.2 GHz with a local oscillator at 9.80
GHz. Front panel LEDs provide indication of DC Power, External 10 MHz, and PLL Alarm. The gain is -30
dB. Connectors are 2.92mm female for RF In, Super SMA female for RF Out and BNC female for the external
reference input and reference output. A three-way switch controls which 10 MHz reference is being used.
When 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 2116 is powered by a 100-240 ±10% VAC power supply, and
mounted in a 1 3/4” X 19” X 14” rack mount chassis.
