States (FCC) and Canada under Industry Canada (IC) Radio Standards Specification (RSS) RSS-210 and RSS-Gen. The modular approval allows the end user to place either an A1101R09A or an A1101R09C with an approved antenna inside a finished product without having to perform costly regulatory testing for an intentional radiator. -
Page 3: Theory Of Operation
1.4. Theory of Operation The A1101R09A and A1101R09C are for low power wireless applications in the US 902 – 928MHz ISM band. The devices can be used to implement a variety of networks, including; point to point, point to multipoint, peer to peer and mesh networks The A1101R09A and A1101R09C both interface to an application microcontroller via SPI bus. - Page 4 Anaren AIR Module, Users Manual depend not only on the antenna, but also the ground plane, enclosure and installation environment. • Filtering Filtering removes spurious signals to comply with regulatory intentional radiator requirements. • Matching The matching provides the correct loading of the transmit amplifier to achieve the highest output power as well as the correct loading for the receive LNA to achieve the best sensitivity.

“Intentional Radiators”. The devices meet the requirements for modular transmitter approval as detailed in FCC public notice DA 00-1407 Released: June 26, 2000. The A1101R09A and A1101R09C module can be integrated into a finished product with obtaining subsequent FCC approvals. -
Page 9: End User Manual
If the A1101R09A and A1101R09C module is used in a portable application (antenna is less than 20 cm from persons during operation), the end user is responsible for performing Specific Absorption Rate (SAR) testing in accordance with FCC rules 2.1091. -

Using the radio modules outside of these limitations are prohibited and could void the user’s authority to operate the modules. The user should use one of the register configurations listed below. Anaren provides register setting files for optimal performance and compliance for each of the data rates given in the following at www.anaren.com. -
Page 12: Usa & Canada
Anaren AIR Module, Users Manual 2.4.1. USA & Canada For use in USA and Canada the modules have been approved for use as digitally modulated transmitters, for which they must have a minimum occupied bandwidth (6dB) of 500kHz. In addition the spectral density may not exceed 8dBm/3kHz and the total output power including antenna gain may not exceed 1W. -

3.3. Pin Out The A1101R09A and A1101R09C radio’s share a common pin-out and foot print, that is also shared by Anaren modules using other frequencies. Thus enabling easy changeover from one to another, e.g. if it is desired to change the frequency or antenna scheme or if the adaptive antenna tuning is needed. Below the common footprint are shown. - Page 14 Anaren AIR Module, Users Manual Pin # Pin Name Pin Type Description Do Not Connect. Internal GND connection used during testing, not recommended to connect to main GND. Do Not Connect. Internal RF output connection used during test. Connecting this pin to anything will require recertification for intentional radiators.

Page 18: Power Supply Considerations
The A1101R09A and A1101R09C radio modules have integral ferrite bead in the supply line from pin 18 (Vdd) and decoupling capacitance to reduce any noise on the incoming power supply line. This arrangement will take care of most supply voltage noise.
