... A typical circuit consists of a low-cost microcontroller, a power source, a Wi.M900X/T module, and an antenna. The WiM900X module is a complete transceiver while the WiM900T module is transmit only. In addition, the modules can be ordered for operation in the 868 MHz band by substituting 868 for 900 ...

... The Wi.M900T is only populated with the transmitter components; it does not have the SAW filter nor the RF switch. On the Wi.M900X the antenna pin on the module goes either to the SAW filter or to the RF switch directly. The module can be ordered with or without a SAW filter. If the SAW filter is populated critical that the antenna be AC coupled if it has a DC path to ground (which is true for most PCB antennas) ...

... Internally, the XE1203 has two identical sets of programming registers (SWParam) that control the operation of the chip. Generally, one set is programmed for receive mode and the other set is programmed for transmit mode. For the Wi.M900X/T module, set 1 is for receive mode and set 2 is for transmit mode. ...

... The output of the VCO is amplified by the power amp, which can be set to one of four output power levels. For detailed information about programming the Wi.M900X/T module, please consult the current XE1203E(F) data sheet which can be found at www.xemics.com. Programming Interface The serial programming interface is compatible with any hardware or software implementation of a SPI serial port ...

... The channel programming word is determined by chanDTS[channel]. The calibration constant is then read in using the I2C bus stored in offset. The offset is then added to the channel programming word and sent to the Wi.M900X/T module using the programming interface. © 2004, 2005 All Rights Reserved www.radiotronix.com ...
