RF Interface
3.13.1
RF Interface Characteristics
The nominal impedance value is 50
Ω
. The DC impedance is 0
Ω
, connected to GND.
The RF connector is a MMCX (Miniature Micro Connector) type. (See section "Supplier Information", 8.1.2)
MMCX connector characteristics and benefits:
•
Standard
type
•
Small physical size type
•
Easy-to-find
product
An antenna can be directly connected through the mating connector or using a small adaptor if necessary
(MMCX-SMA for example) (see section "Supplier Information", 8.1.2).
The MMCX connector incorporates a 'snap-on' latching action in order to make connection easier with
excellent RF performance. This type of connector is suitable for the standard ranges of flexible and semi-
rigid cables.
3.13.2
