Ground connection

When connecting the module to system ground:

•

Prevent noise leakage by establishing a very good ground connection to the 
module through the host connector.

•

Connect to system ground using the two mounting holes at the top of the 
module (shown in 

Figure 5-1 on page 39

).

•

Minimize ground noise leakage into the RF.

Depending on the host board design, noise could 

potentially

 be coupled to 

the module from the host board. This is mainly an issue for host designs that 
have signals traveling along the length of the module, or circuitry operating at 
both ends of the module interconnects.

Interference and sensitivity

Several interference sources can affect the module’s RF performance 
(RF desense). Common sources include power supply noise and device-
generated RF.

RF desense can be addressed through a combination of mitigation techniques 
(

Methods to mitigate decreased Rx performance on page 42

) and radiated 

sensitivity measurement (

Radiated sensitivity measurement on page 43

).

Note:  The MC7710 is based on ZIF (Zero Intermediate Frequency) technologies. When 
performing EMC (Electromagnetic Compatibility) tests, there are no IF (Intermediate 
Frequency) components from the module to consider.

Interference from other wireless devices

Wireless devices operating inside the host device can cause interference that 
affects the module.

To determine the most suitable locations for antennas on your host device, 
evaluate each wireless device’s radio system, considering the following:

•

Any harmonics, sub-harmonics, or cross-products of signals generated by 
wireless devices that fall in the module’s Rx range may cause spurious 
response, resulting in decreased Rx performance.

•

The Tx power and corresponding broadband noise of other wireless devices 
may overload or increase the noise floor of the module’s receiver, resulting in 
Rx desense.

The severity of this interference depends on the closeness of the other antennas 
to the module’s antenna. To determine suitable locations for each wireless 
device’s antenna, thoroughly evaluate your host device’s design.

Host-generated RF interference

All electronic computing devices generate RF interference that can negatively 
affect the receive sensitivity of the module.
