The Power Amplifier board incorporates a dual port directional coupler. The coupler measures
the forward and reverse transmitter power. The coupler is used to measure the voltage standing
wave ratios (VSWR) of the antenna. If the VSWR exceeds a 2.0:1 ratio, the transmitter shuts
down, preventing the unit from transmitting into an improper load or open circuit. This protects
the output transistor from a catastrophic failure.
6.4 Internal GNSS daughter board (optional)
The X5 Daughter Board mounts directly inside the MRC565 radio on a modified MRC565 CMU
board. Modifications to the CMU board include removing the Ublox GPS module, adding a 12-
pin header connector and adding a 3.3V power regulator. The 12-pin header connector has a
3.3VDC, 5VDC, two RS232 ports, SPI port and PPS. The X5 Daughter board includes a
Septentrio Mosaic X5 chip, mating 12 pin connector, Ethernet control chip and an Ethernet jack.
Two jumpers (JP3, JP4) have been added to the CMU board allowing operator to select which
serial port will be sacrificed for X5 Daughter board operation and which will remain connected
to the 44-pin connector. For an MRC565 configured as a remote without the X5 Daughter
board, both jumpers are set to connect Aux and DTA to 44 pin connectors.
For an MRC565 configured as a remote with the X5 Daughter board, the AUX jumper will be set
connecting Aux serial to X5 Daughter board internally and leaving the DTA connected to the
44pin connector.
When configured as a base there are two options.
1. connect both AUX and DTA serial ports to X5 Daughter board, keeping both the
NMEA and RTCMv3 streams connected to CMU board internally.
2. use IP sockets to connect X5 Daughter board to the CMU board. For this option will
need an external ethernet switch.
The X5 Daughter board Ethernet jack also allows operator to access Mosaic X5 daughter boards
internal Configuration Web Page via a new M8 Ethernet connector added to the front panel of
the MRC565.
