8.1 Antenna Considerations

Table 8.2 provides the list of antennas along with the

manufacturer and part number details.

TABLE 8-2: ANTENNA LIST

Table 8.3 provides the antennas to be used for the

various SKUs as per Table 8.2.

TABLE 8-3: ANTENNAS FOR VARIOUS

SKUs

8.2 CY920 Usage Guidelines under

Modular Approval

The CY module has received Limited Module

Approval (LMA) from FCC and IC. This is because the

CY module does not have complete built-in Power

regulator circuit. Microchip recommends that

customers follow the supply voltage requirements

provided in this data sheet, and follow the Power

supply design provided in the “CY Module Power

Supply V1.0” document. It is the product manufacturer

responsibility to ensure that the power supply

recommendations are followed, and the RF behavior

adheres the FCC or TCB certification requirements

when the module is installed in the final Host product.

The product manufacturer should work with their test

house for confirming the RF behavior with FCC or TCB.

8.3 Restriction of Use of Hazardous

Substances (RoHS) Compliance

CY920 module uses only RoHS compliant components.
