5.2 Power Supply
Each SSPA may contain up to two 28V (depending on the power level of the SSPA)
power supplies, to supply power to the waveguide switch. The state of the 28V power
supplies (referred as “Boost1” and “Boost2”) can be monitored from the SSPA front
panel display or through the remote serial protocol. Power supplies are fully protected
from over-current and over-voltage conditions and can reliably output up to 3A of DC
current.
5.3 RF Switches
The SSPA redundant system controls a -28V waveguide/coaxial switch using the 6-pin
rear panel connector J3. The switches are controlled by ap28V to the common
of the switch and pulsing either position to the ground. The system then verifies the
position of the switch.
5.4 Switch Connector
The 6-pin connector J3, Molex P/N 43810-002 can be located on the SSPA rear panel.
This connector is used to interface with the RF switches. Teledyne Paradise Datacom
recommends the following parts to build a mating pair to this connector (all P/N by
Molex): Pin Crimp: 39-00-0039; receptacle: 39-01-2060; strain relief: 15-04-0296.
Table 5-1
shows the proper wiring to the MS3116F10-6S RF switch connector,
commonly used on waveguide switches.
Figure 5-2
shows an outline drawing of a
typical switch connector cable.
