RF interface
The antenna interface is a 50
Ω
coaxial connector. Matching networks are not included on the
module and should be placed in the host application if the antenna is not 50
Ω
. The HIROSE
U.FL compatible connector is located on the TOP side of the board.
NOTE! The used connector has gold plated contacts - whereas a standard HIROSE U-FL has
silver plated contacts.
If silver - gold joints are not allowed in your product, use gold plated cable-connector to mate to
this device.
NOTE!
Setting the transmitter output power to such a level that exceeds the regulations set forth by
local authorities is strictly forbidden. The setting and/or using of non-approved power levels
may lead to prosecution. SATEL and its distributors are not responsible for any illegal use of
its radio equipment, and are not responsible in any way of any claims or penalties arising
from the operation of its radio equipment in ways contradictory to local regulations and/or
requirements and/or laws.
