APPROVED EXTERNAL ANTENNA TYPES
Transmitter Antenna (from Section 7.1.2 RSS-Gen, Issue 5) The 888 module can only be sold
or operated with antennas with which it was approved. Transmitter maybe approved with
multiple antenna types. An antenna type comprises antennas having similar in-band and out-of-
band radiation patterns. Testing shall be performed using the highest gain antenna of each
combination of transmitter and antenna type for which approval is being sought, with the
transmitter output power set at the maximum level. Any antenna of the same type having equal
or lesser gain as an antenna that had been successfully tested with the transmitter, will also be
considered approved with the transmitter, and may be used and marketed with the transmitter.
When a measurement at the antenna connector is used to determine RF output power, the
effective gain of the device's antenna shall be stated, based on measurement or on data from
the antenna manufacturer. For transmitters of output power greater than 10 milliwatts, the total
antenna gain shall be added to the measured RF output power to demonstrate compliance to
the specified radiated power limits
RF Trace Layout Design
The modular transmitter is certified with a PCB edge SMA connector and micro-strip trace layout as shown
in the figure. The left side RF path is not used for this module. The host PCB can follow these trace design
to maintain compliance under the modular grant (FCC) and certificate (IC).
