NJRC strives to produce reliable and high quality microwave components.NJRC's microwave components are intended for specific applications andrequire proper maintenance and handling. To enhance the performanceand service of NJRC's microwave components, the devices, machinery orequipment into which they are integrated should undergo preventativemaintenance and inspection at regularly scheduled intervals. Failure toproperly maintain equipment and machinery incorporating these productscan result in catastrophic system failures.

To ensure the highest levels of reliability, NJRC products must always beproperly handled. The introduction of external contaminants (e.g. dust, oilor cosmetics) can result in failures of microwave components.

NJRC offers a variety of microwave components intended for particularapplications. It is important that you select the proper component for yourintended application. You may contact NJRC's sales office or salesrepresentatives, if you are uncertain about the products listed in thecatalog and the specification sheets.

Special care is required in designing devices, machinery or equipment,which demand high levels of reliability. This is particularly important whendesigning critical components or systems whose foreseeable failure canresult in situations that could adversely affect health or safety. Indesigning such critical devices, equipment or machinery, carefulconsideration should be given to, amongst other things, their safetydesign, fail-safe design, back-up and redundancy systems, and diffusiondesign.

The products listed in the catalog and specification sheets may not beappropriate for use in certain equipment where reliability is critical orwhere the products may be subjected to extreme conditions.

6.2. Connecting ModemThe Unit is connected the modem.

Step 1:

Location of Coaxial Connector

The Unit receives the reference and the IF signal and is required to supply+15 to +30 V DC power from the modem via coaxial cable.

When connecting the coaxial cable from the modem, follow the followingsteps:

Connect the coaxial cable with the N or F-type male connectorsto the coaxial connecter equipped with the Unit which is shownin a figure below under 0.68 to 1.13 N・m torque.

Use self-amalgamating tape to seal connector and cable entrypoints from the connector to the cable sheath.

Supplied the IF/Ref./DC Power via Coaxial Cable


Step 1:

Fixing a ground wire from the common ground of other equipments forgrounding is proceed with the following step:

Fix the ground wire from other equipments to the ground holenear the coaxical connector with enclosed on the Unit which isshown in a figure below.

To reduce the risk of damage or broken by lightning surge, theUnit should be fixed with the ground wire.

6.2.2. Fixing Ground WireThe Unit should be common with ground of other equipments (e.g.antenna).
