SEMCO Proprietary Information
9
The in-line +30 dBm and +37 dBm RF Power Amplifier modules are installed and used as shown in Figure 2-9.
The module attachment uses the same footprint and hole alignment as the
Dual RF Output and Dynamic
Combiner Test module. The design of these 2 options precludes their simultaneous use based upon their
respective test application in a Telemetry Ground Station environment. The RF High Power feature is designed
for use at some distance outside the Telemetry Ground Station, and the Dual RF Output and Dynamic Combiner
Test feature is used umbilically inside the Telemetry Ground Station for receiver diversity combiner testing.
A Lemo connector cable provides RF Amplifier power, cooling fan power, sensing and control line from the
PHTS housing (next to RF “N” connector). The PHTS108 “senses” when the Power amplifier is installed and
automatically changes the output level readings accordingly. A short RF cable with “N” (M) connectors is used
between the PHTS RF Output and the RF Power Amplifier RF Input. The antenna is then attached to the RF
Amplifier’s RF output.
