M10 Hardware Design
4 Antenna interface
The Pin 43 is the RF antenna pad. The RF interface has an impedance of 50Ω.
4.1 Antenna installation
M10 provides an RF antenna PAD for customer’s antenna installation. The customer’s antenna
should be located in the customer’s main board and connect to module’s antenna pad through
microstrip line or other type RF trace which the impendence must be controlled in 50Ω. To help
the customer to ground the antenna, M10 comes with 2 grounding pads located close to the
antenna pad.

If the customer installs the antenna via a soldered microwave coaxial cable, we would suggest the
customer to choose RF cable carefully so as to minimize the loss on the RF cable. And the
recommended insertion loss should try to meet the following requirements:
z GSM850/EGSM900<0.5dB
z DCS1800/PCS1900<1dB
