2.2 U6300 interface application

U6300 supplies multifold functional interface by a Mini PCIe Interface, such as , USIM card interface, USB interface,

audio interface*, UART interface*, PCM（Pulse Code Modulation） interface*, IIC interface* and power supply

interface and so on. The detail information will be given in the follow sections.

2.2.1 RF antenna interface

The impedance of RF antenna is 50Ω.

The three connector is on the top of U6300;

For minimizing the wasting of RF cable, user should pay more attention to make choice. We suggest choosing the cable

that satisfies:

• GSM850/900<1dB

• DCS1800/PCS1900<1.5dB

• UMTS2100/ UMTS1900/ UMTS850<1.5dB

And the antenna should satisfy the table below：
