General

-----------

The modules is a low power radio frequency module operating within the ISM 2.4 GHz frequency

band. The radio transceiver is compatible with IEEE.802.15.4 standard with hardware acceleration for

both the IEEE 802.15.4 MAC and AES security.. It also incoproates a 32-bit ARM7 core based MCU, 128

Kbyte FLASH memory and 96 Kbyte RAM. It is intended for use as a short range radio module

for embedded applications.

Block Diagram Fig. 1 Block Diagram RF Operation The RF radio interface provides for low cost and the high density as shown in Figure 2. The transceiver is a zero IF radio without intermediate frequency (IF)stage. An onboard balun along with a TX/RX switch allows direct connection to a single-ended 50-Ω antenna. The integrated PA provides programmable output power typically from -30 dBm to +4 dBm, and the RX LNA provides -96 dBm sensitivity.
