Theory of Operation:
The functional block diagram for each antenna option for ISM14585-L35-P8 RF module is
shown above. This module is a direct sequence spread spectrum transceiver operating in
the 2.402 GHz to 2.480 GHz ISM band. Channels are spaced at 2 MHz intervals in the ISM
band. There are a total number of 40 channels. The system operates at a chip rate of
1Mbps, a sample rate between 8 kHz and 48 kHz and a bit rate of 1000kbps. GFSK
modulation is used with DSSS. An input supply of 3.0 VDC is supplied to the RF module
using a battery or external power supply.
