6.4. Si4770Module-A-EVB
Separately from the Si477x-EVB kit, user's may also order an Si4770Module-A-EVB kit. The Si4770Module-A-EVB
kit consists of an Si4770 Module and Si477x Interposer card. Together, these serve in place of a daughter card on
an Si477x EVB. Alternatively, the Si4770 Module can be installed into a user-created system with a compatible
pinout. To use the Si4770Module-A-EVB in conjunction with an Si477x EVB, connect the module, interposer card,
and baseboard as shown in Figure 34.
Note: The Si4770 Module is configured by default for an AM Loop Antenna connected through the Si47xx Interposer card. For
optimum results in conducted tests through the AM Test SMA connector, remove transformer T2 from the AM signal path
on the Si4770 Module.
