2.2 Interface Connectors
2.2.1 TX (RF) In Connector, J1
The J1 RF Input connector is a 50ohm Type ‘N’ female connector. Labeled “TX
IN”, typical input levels (+0 to ~ + 20 dBm) depend on desired output power.
For example, if the unit has a gain of 40dB, then an input level of +15 dBm will
result in an output of 55dBm. In general, RF input levels above those which
result in output saturation (>> Prated) should be avoided and to prevent damge to
the TRP500, should never exceed +30 dBm.
2.2.2 RF Out Connector, J2
For safety reasons, never look directly into the waveguide output. Also, never
apply power to the unit without an appropriate termination/connection to the
waveguide flange.
The J2 RF Out connector is a waveguide flange interface, as shown in Figure 2-1. The
interface is CPR187G. Be careful to not allow any unwanted material to enter the waveguide
output while the interface is open. The opening is covered with a protective material during
shipment. Use the supplied gasket (assumed mating flange = CPR187G) to ensure a watertight
connection, and make sure the screws used to secure the mating flange do not bottom out.
2.2.3 AC Power Main Connector, J3
The AC prime power input requirements for the TRP500 are as follows:
• 180-264 VAC
• 47 to 63 Hz
The power supply is power factor corrected. The total power required from
the prime power supply is listed in the Sect. 1.5 Summary of Specifications.
The mating connector specification and the pin assignments (Table 2-1) for
the TRP500 AC power interface are as follows:
Mating Connector: CEFD PN CN/MS-STPG03F07 (Glenair ITS3106F20-
19SF7).
