Reference Circuits Connect the RFIO and ANT terminals with the shortest possible length of 50Ω transmission line. Connect the DCC and DEC4 pins as shown in Figure 5-1 when using the built-in LDO and Figure 5-2 when using the built-in DC/DC converter. Regardless of the circuit connection status, a register setting by software is required.

Absolute maximum ratings are standards that must not be exceeded even momentarily. Exceeding the absolute maximum ratings may cause deterioration or damage to internal components and may also destroy, damage, or degrade external circuits other than the module. The application equipment should be designed to ensure that the absolute maximum ratings are not exceeded under any operating conditions. Table 6-1 Absolute maximum ratings *2. Be sure to connect a bypass capacitor near the module for use. *3. The on-chip power-on reset circuitry may not function properly for rise times longer than the...

This product has obtained construction design certification as a radio station for low-power data communication system based on the Radio Law. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Warning: Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. The Integrator will be responsible...

8.1.2.7 FCC Statement (OEM) Integrator has to assure compliance of the entire end-product incl. the integrated RF Module. For 15 B (§15.107 and if applicable §15.109) compliance, the host manufacturer is required to show compliance with 15 while the module is installed and operating. Furthermore the module should be transmitting and the evaluation should confirm that the module's intentional emissions (15C) are compliant (fundamental / out-of-band). Finally the integrator has to apply the appropriate equipment authorization (e.g. Verification) for the new host device per definition in §15.101....
