1. Overview
The description of the functional blocks shown in Figure 1 is given as follows:
• Antenna: The antenna couples energy between the air and the module. The integral antenna and the external
monopole antenna—both centered at 2441.75 MHz—provide a near-omni-directional antenna pattern with
high efficiency, such that the application will work in any direction. The end radiation pattern of the antenna
depends on the ground plane, enclosure, and installation environment.
•
Matching and Filtering: The matching provides the correct loading of the transmit amplifier to achieve the
highest output power and the correct loading for the receive LNA to achieve the best sensitivity. Filtering
removes spurious signals to comply with regulatory requirements, provides reduced susceptibility to power
supply and digital noise, and filters out RF and high-frequency noise from the communication data and control
link.
• TX/RX Chain: The TX/RX chain handles transmitting and receiving of the communication data based on the
radio register settings. It involves the coordination of several blocks, including the modulator, demodulator,
AGC control, frequency synthesizer, and frame control.
• Crystal: The crystal oscillator provides the necessary clock reference for the entire module operation. The
A43364x modules use two 26 MHz crystals: one for the radio and one for the microcontroller.
• Power Management: Power management ensures a stable supply for the internal functions, as well as providing
means for a low-power sleep mode.
