Connecting the Antenna to the Receiver
Connect the antenna to the receiver using a high quality coaxial cable (as discussed in
on page 77 for antenna power requirements.
For the OEM615, an interconnect adapter cable is required to convert the end of the coaxial
cable to the card’s MCX female RF input connector. The RF connector location for the OEM615
is shown in
Figure 10, OEM615 Connector and Indicator Locations
on page 35. A user supplied
LNA_PWR supply is internally regulated to 5 VDC and sent to the center pin of the MCX RF
connector to power an external antenna (the return is the outer conductor of the coax).
The antenna port is capable of providing up to 100 mA to a connected antenna (based on a 6 V
input supply). Higher input voltages should follow the derating curve (refer to
OEM615 Technical Specifications
on page 113 for antenna details). The typical current draw for
a NovAtel antenna is less than 40 mA.
For the OEM617, an interconnect adapter cable is required to convert the end of the coaxial
cable to the card’s MCX female RF input connector. The RF connector location for the OEM617
is shown in
Figure 11, OEM617 Connector and Indicator Locations
on page 36. A user supplied
LNA_PWR supply is internally regulated to 5 VDC and sent to the center pin of the MCX RF
connector to power an external antenna (the return is the outer conductor of the coax).
The antenna port is capable of providing up to 200 mA to a connected antenna (based on a 6 V
input supply). Higher input voltages should follow the derating curve (refer to
OEM617 Technical Specifications
on page 125 for antenna details). The typical current draw for
a NovAtel antenna is less than 40 mA.
For the OEM617D, an interconnect adapter cable is required to convert the end of the coaxial
cable to the card’s MMCX female RF input connector. The RF connector location for the
OEM617D is shown in
Figure 12, OEM617D Connectors and Indicators
on page 36. A user
supplied LNA_PWR supply is internally regulated to 5 VDC and sent to the center pin of the
MMCX RF connector to power an external antenna (the return is the outer conductor of the coax).
The antenna ports are capable of providing up to 100 mA to a connected antenna (based on a 6
V input supply). Higher input voltages should follow the derating curve (refer to
OEM617D Technical Specifications
on page 135 for antenna details). The typical current draw
for a NovAtel antenna is less than 40 mA.
For the OEM628, an interconnect adapter cable is required to convert the end of the coaxial
cable to the card’s MMCX female RF input connector. The RF connector location for the
OEM628 is shown in
Figure 13, OEM628 Connector and Indicator Locations
The OEM628 has an internal 5 V LNA_PWR supply, limited to 100 mA.
Appendix D, OEM628 Technical Specifications
on page 145 for details.
For the OEM638, an interconnect adapter cable is required to convert the end of the coaxial
cable to the card’s MMCX female RF input connector. The RF connector location for the
OEM638 is shown in
Figure 14, OEM638 Connector and Indicator Locations
The OEM638 has an internal 5 V LNA_PWR supply (limited to 200 mA) and an optional LNA
supply that goes to the antenna with no regulation or derating.
Appendix E, OEM638 Technical Specifications
on page 162 for details.
