2.3.15.7 HPA/TSC Transmit Output Coupler/RF Detector
The WG WR
340 HPA/TSC transmission output coupler with RF detector is the final component
in the HPA sub-system’s transmission path. The HPA/TSC transmit output coupler is
connected to the magic tee’s output interface for forward and reflected power level
measurements.
The HPA/TSC transmit output coupler with RF detector includes two (2) coupled forward
ports, one (1) coupled reflected port and an RF detector board (which is located inside a
weatherproof housing).
The RF detector performs forward and reflected power monitoring/detection using forward
and reflected power detection circuits, which are connected to a coupled forward port and a
coupled reflected port respectively. The detected power levels are reported to the TSC via a
RS-485 interface.
The remaining coupled forward port is used to provide a forward power sample to the exciter.
An HPA/TSC transmit output coupler is also connected to each of the magic tee input
interfaces, for forward and reflected power level measurements on each HPA set.
