5.3.3 RF C
ONNECTIONS
The following three RF connections are made at the SSPA:
•
RF input (J1) – Type-N Female provided at the front panel. User needs Type-N male on
interface connection.
•
RF output monitor (J4) – Type-N Female, see
Figure 3
at page 14. User needs Type-N male
on interface connection.
•
RF Output (J7) - Waveguide connection WR-75 G (grooved). A waterproof gasket is
provided in the shipping kit.
To install the waveguide output flange, proceed as follows:
1. Install
the
waterproof
gasket (supplied) at the output flange of the SSPA.
2. Position the interconnecting flange so that it aligns precisely with the waveguide flange at
(J7).
3. After alignment is verified, loosely attach the interconnecting waveguide to the output
waveguide flange of the SSPA. Start all bolts (supplied) and verify proper alignment before
uniformly tightening the bolts.
4. Carefully tighten all bolts (in opposite pairs rather than sequentially around the perimeter of
the flange) so that the connection is firm. Do not over-tighten because this can strip the
threads or distort the mating flange. Recommended torque is 15 in-lbs for #6-32 bolts.
NOTE:
Wrap the mastic tape (provided in the shipping kit) around all connectors in order to
prevent water/humidity ingress and resultant damage. Squeeze the tape tightly and ensure that
both ends of the tape have formed around the connector and the cable.
CAUTION:
Beware of destructive Pin Depth of Mating Connector.
When an RF
component connector is mated with a connector having a destructive pin depth, damage will
usually occur to the RF component connector. A destructive pin depth is one that is too long
in respect to the reference plane of the connector. The center pin of the connectors used by
ADVANTECH has a precision tolerance measured in mils (1/1000 inch). The mating
connectors of various suppliers may not be precision types. Consequently, the center pins of
these devices may not have the proper depth.
