center pin provides +9.5 VDC (to power the LNA) and accepts 1575 MHz or 1227.60
MHz RF input from the antenna; the RF and DC signals share the same path.
Power Input Connections
Two 3-pin Fischer connectors wired in parallel provide the power input interface.
Table 2.2 defines the pinout of the power connector. Figure 2.3 shows the pin layout
of the power connector.
CAUTION
The current is limited to 150 mA out of the RF center conductor. It is
short-circuited protected. If using a splitter or other RF network, use an
inner DC block suitable for 1-2 GHz, 50 ohms, maximum voltage 25 V
to protect the Sensor from external voltages.
