3. Characteristics

All MIN/MAX specification limits are guaranteed by design, production testing and/or statistical characterization. Typical values are based on characterization results at default measurement conditions and are informative only. Default measurement conditions (unless otherwise specified): VDD_IN = 3.6 V, VDD_IO = 1.8V, TA = 25 . All radio measurements are performed with standard RF measurement equipment.

3.1. Absolute Maximum Ratings

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, so functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specification are not implied. Exposure to Absolute Maximum Rating conditions for extended periods may affect device reliability.

Datasheet

The modular transmitter is only FCC authorized for the specific rule parts (FCC Part 15.247) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. The final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed when contains digital circuity.
7.2. FCC Statements

(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.
Integrator is reminded to assure that these installation instructions will not be made available to the end-user of the final host device.
The final host device, into which this RF Module is integrated” has to be labeled with an auxiliary label stating the FCC ID of the RF Module, such as “Contains FCC ID: 2ABRU-2564C
“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.”
“Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.”
The Integrator will be responsible to satisfy SAR/ RF Exposure requirements, when the module integrated into the host device.

7.3. Module statement

The single-modular transmitter is a self-contained, physically delineated, component for which compliance can be demonstrated independent of the host operating conditions, and which complies with all eight requirements of § 15.212(a)(1) as summarized below.
(1) The radio elements have the radio frequency circuitry shielded. (2) The module has buffered modulation/data inputs to ensure that the device will complywith Part 15 requirements with any type of input signal. (3) The module contains power supply regulation on the module.
