A1101L09x – Users Manual Release Date 11/01/11 Page 5 of 40 1. Overview The A1101L09A and A1101L09C are surface mount modules – each with an integrated crystal, internal voltage regulator, Low Noise Amplifier, matching circuitry and filtering. The A1101L09A has an integral antenna, whereas the A1101L09C utilizes an external antenna through a U.FL connector (see Table1.).

A1101L09x – Users Manual Release Date 11/01/11 Page 7 of 40 To transmit, a frame of data is placed in the FIFO; this may include a destination address. A transmit command is given, which will transmit the data according to the initial setup of the registers. To receive data, a receive command is given, which enables the unit to “listen” for a transmission; when such a transmission occurs, it places the received frame in the FIFO.
Page 8 of 40 A1101L09x – Users Manual Release Date 11/01/11 Microcontroller Interface o The microcontroller interface exposes registers and commands for the physical and MAC layers to a microcontroller. Power Management o Power management ensures a stable supply for the internal functions, as well as providing means for a low power sleep mode (in which case, most of the transceiver is power off).

Typical Flow After initial setup of registers for desired behavior, the normal operation flow diagram is shown in Figure 4. In applications of infrequent data transmissions, the transceiver would be in “sleep” mode to save power (400nA). From there it would wake up and then enter “idle” mode.

A1101L09x – Users Manual Release Date 11/01/11 Page 16 of 40 From section 7.1.4, RSS-Gen, Issue 3, December 2010, Radio Apparatus Containing Digital Circuits (ICES-003): “Radio apparatus containing digital circuitry which can function separately from the operation of a transmitter or an associated transmitter, shall comply with ICES-003. In such cases, the labeling requirements of the applicable RSS apply, rather than the labelling requirements in ICES-003.
A1101L09x – Users Manual Release Date 11/01/11 Page 17 of 40 2.3.1. Time critical data If the user requires specific time critical data throughput that cannot tolerate the delays of potentially many re-transmissions, the user is encouraged to implement an environment-aware algorithm that periodically monitors/scans the frequency band and maintain a list of “best available” channels. 2.4.

Absolute Maximum Ratings Under no circumstances must the absolute maximum ratings given in Table 4 be violated. Stress exceeding one or more of the limiting values may cause permanent damage to the device. Caution! ESD sensitive device. Precaution should be used when handling the device in order to prevent permanent damage.
A1101L09x – Users Manual Release Date 11/01/11 Page 20 of 40 3.2. Operating Conditions Table 5 Operating Conditions Note: As the voltage increases in pin 24 (Vctrl2) the Gain of the Module increases. It’s been recommended that in order to maintain a constant Gain a supply voltage from 2.9 to 3.1V to pin 24 (Vctrl2). 3.3. Pin Out The A1101L09A and A1101L09C radio modules share a common pin-out.

A1101L09x – Users Manual Release Date 11/01/11 3.5. Page 25 of 40 Power Supply Considerations Noise on the power supply line reduces the sensitivity of a receiver and modulates onto a transmitter’s signal, both of which causes a degradation of link quality and hence a reduction in range. The A1101L09A and A1101L09C radio modules each have an integral ferrite bead in the supply line from pin 21 (Vdd) and decoupling capacitance to reduce any noise on the incoming power supply line.

Figure 9 Delay caused by LNA to turn off LNA Operation The A1101L09A and A1101L09C radio modules are equipped with LNA which needs a control mechanism to both power the LNA and the receive side of the Tx/Rx switch (V+). It also requires an inverted voltage to control the Radio module actively in receive mode.

A no-clean tin/silver/copper (SAC) solder is recommended, however lead based no-clean pastes may also be used. CAUTION: AIR Modules are designed for no-clean fluxes only. DO NOT use waterbased fluxes that require aqueous cleaning after solder.
