UIDELINES
The following is a list of RF layout design guidelines and recommendation when installing a Summit radio into
your device.

Do not run antenna cables directly above or directly below the radio.

Do not place any parts or run any high speed digital lines below the radio.

If there are other radios or transmitters located on the device (such as a Bluetooth radio), place the
devices as far apart from each other as possible.

Ensure that there is the maximum allowable spacing separating the antenna connectors on the Summit
radio from the antenna. In addition, do not place antennas directly above or directly below the radio.

Summit recommends the use of a double shielded cable for the connection between the radio and the
antenna elements.

EGULATORY
Certified Antennas
The SDC-SSD30AG provides two antenna interfaces to support transmit and receive diversity. For single
antenna, non-diversity applications, OEMs are advised to use the Main (pin 10) antenna interface and should
disable transmit and receive diversity from the Global tab of the Summit Client Utility (SCU) software utility.
Summit does not have specific regulatory approvals for the SDC-SSD30AG. Summit has regulatory approvals
for the SDC-MSD30AG which is a PCB module that is based on the SDC-SSD30AG. As such, the ETSI, FCC,
and Industry Canada final test reports for the SDC-MSD30AG may be leveraged when pursuing approvals for
host devices that incorporate the SDC-SSD30AG. The SDC-MSD30AG tests were conducted with the
following antennas:
CiscoAIR-ANT 4941 (click for datasheet)

Form Factor: Whip

required in the 2.4 GHz band)
Radiall Larson Dipole (click for datasheet)

Form Factor: Whip

Type: Dipole

Maximum 2.4 GHz Gain: 1.6 dBi*

Maximum 5 GHz Gain: 5 dBi

Tested and Certified 5 GHz Transmit Power: 100% of maximum setting (no reduction of power is
required in the 5 GHz band)
Note: This antenna was only used for 802.11a (5 GHz) testing.
