Model 2009-2425-1750 Downconverter
2.40 - 2.50 GHz to 1700 - 1800 MHz
1.0 General
1.1 Equipment Description
The 2009-2425-1750 Downconverter converts a 2.40 - 2.50 GHz signal to 1700 - 1800 MHz
with a low side local oscillator (LO) (non-inverted spectrum). Featuring low phase noise and
high stability, this unit down converts 2.40 - 2.50 GHz signals to 1700 - 1800 MHz. The 2.40 -
2.50 GHz input is mixed with a synthesized local oscillator (LO) signal to 1700 - 1800 MHz.
The mixer output is applied to the output amplifier providing a nominal gain of +10 dB.
Connectors are 75Ωtype-F (female) for the 1700 - 1800 MHz output and 50Ωtype-N (female)
for the RF input. Front panel LEDs light when DC power is applied (green) and when a PLL
alarm occurs (red). DC power is provided by the LNB voltage from the receiver under test or by
an external wall mount power supply (option -P4). The 2009 can be mounted on an 1 3/4” X
19” rack mount panel (option -R)

2.0 Installation
2.1 Mechanical
The 2009-59 is packaged in an aluminum extrusion. The -R option is mounted on a 1 3/4” X 19” panel that can
be mounted to a rack using the 4 holes at the ends (See Figure 2.1).
2.1.1 Cleaning Instructions
Wipe the exterior with a dry, soft cloth. Use no detergent or cleaning chemicals.

2.4 Accessing the PC Card
There are NO USER JUMPERS or other on-card controls. ALTHOUGH IT IS NOT RECOMMENDED AND
MAY VOID THE WARRANTY the following shows how to remove the printed circuit board (PCB) from the
extrusion:
1. Always remove power when installing or removing the PCB from the extrusion
2. Remove four (4) rear panel screws (see Figure 2.1).
3. Gently pull the rear panel and PCB assembly completely out of the extrusion.
4. To install the PCB, gently push the rear panel and PCB assembly completely into the extrusion
(make sure the shield goes in the lower channel and the PCB in the next channel above that) and that
the front panel indicators line up with the front panel holes.
5. Install four (4) rear panel screws.
2.5 Installation / Operation
2.5.1 Installing and Operating the 2009-2425-1750:
1. For -P4 models, connect one end of the Wall Power Supply to the 2009-2425-1750 DC
Power In, J3, and the other end to 115 VAC, 60 Hz (Figure 2.3).
2. Connect a -20 dBm, maximum, signal to RF IN, J1 (Figure 2.3).
3. Connect the IF OUT, J2, to the receiver under test (For models powered from the LNB be sure that
the LNB voltage is +15 to +18 VDC, 250 ma) (Figure 2.3).
4. Be sure DS1 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.2).
3.0 Environmental Use Information
2009-2425-1750 Manual, Rev. 0 Page 6 09/05/19
A.Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions
located in the user manual furnished by the manufacturer of your equipment rack.
B. Mechanical Loading - Mounting of equipment in a rack should be such that a hazardous condition
does not exist due to uneven weight distribution.
C.Elevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly,
the operating ambient temperature of the rack may be greater than room ambient temperature.
Therefore, consideration should be given to Tmra.
D. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised. Additional space between units
may be required.
E. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply
circuit and the effect that overloading of circuits could have on over current protection and supply wiring.
Appropriate consideration of equipment name plate rating should be used, when addressing this concern.
F. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.
Particular attention should be given to supply connections other than direct connection to the
Branch (use of power strips).
G. Top Cover - There are no serviceable parts inside the product so, the Top Cover should not be removed.
If the Top Cover is removed the ground strap and associated screw MUST BE REINSTALLED
prior to Top Cover screw replacement. FAILURE TO DO this may cause INGRESS and/or EGRESS
emission problems.
