LNR UC6L-D4 C BAND UP CONVERTER 70MHz
FREQUENCY 5.950-6.425 GHz 2.5 MHz STEP SIZE
GENERAL ELECTRICAL DESCRIPTION
The LNR UC6L-D4 C BAND UP CONVERTER 70MHz unit is designed to be completely self contained. including power supplies, highly stable local oscillator sources, RF frequency conversion components and operational monitoring circuitry for all major subassemblies. The monitoring capabilities are presented in the form of front panel illuminated indicators and test points, as well as a rear panel connector supplying the user with a form C relay closure for the purpose of remote alirm summation.
The dual frequency conversion scheme is accomplished by the use of two crystal oscillator referenced phase locked oscillator multiplier chains. The output frequencies of the local oscillators
are presented as front panel BNC connectors and may be used for monitoring purposes. The frequency of the second (RF) local oscillator is synthesized and tunable in 2.5 MHz increments to allow for c~rrier agility across the *5.845 to 6.425 GHz transmit band. The first (IF) local oscillator is designed to be a fixed frequency. resonant cavity mechanically tuned typedevice.
Front panel pushbutton “MODE” selector switches allow the unit to be placed in a manual (Local) c6mmand status. or in a remote status in which the
unit is commanded via rear panel RS422 interface connector J4. The frequency converter unit is prewired for operation at either 115 VAC or 230 VAC. Internal jumpers allow changing between 115 V and 230 V. The power requirement at 115 VAC is approximately 150 W reducing to approximately 100 W after warm up.
