General Description
The WP-MK-X2010 radio transceiver module was designed to provide reliable wireless operation at moderate data rates for use throughout the world. Its unique features of narrower RF channel bandwidths and hence high interference rejection capability at SAW module prices make the X2010 the ideal choice for next generation applications. Available for operation at the major frequency allocations world-wide in the same package, these modules have been designed to provide a reliable wire free link for the next century, accounting for the increased traffic from other legal users of the radio spectrum. The transmitter section uses a PLL design that utilises a highly stable and accurate reference crystal oscillator. This results in a RF transmission tightly controlled in its frequency spread and over its operating temperature range. This is exploited in the receiver design. The receiver section uses a single conversion super-het design, again using PLL technology. Hence narrower bandwidth RF filters are utilised which result in superior rejection of interference as well as providing good receiver sensitivity and hence range.

Application Information
Antenna Design The design and positioning of the antenna is as crucial as the module performance itself in achieving a good wireless system range. The following will assist the designer in maximising system performance. The antenna should be kept as far away from sources of electrical interference as physically possible. If necessary, additional power line decoupling capacitors should be placed close to the module. The antenna `hot end' should be kept clear of any objects, especially any metal as this can severely restrict the efficiency of the antenna to receive power. Any earth planes restricting the radiation path to the antenna will also have the same effect. Best range is achieved with either a straight piece of wire, rod or PCB track @ 1/4 wavelength (15.5cm @ 433.92MHz). Further range may be achieved if the 1/4 wave antenna is placed perpendicular in the middle of a solid earth plane measuring at least 16cm radius. In this case, the antenna should be connected to the module via some 50 ohm characteristic impedance coax.

RSSI Values
The RSSI output provides a dc voltage that is proportional to the RF signal strength picked up on the antenna (pin 2) port of the module. The table below gives typical values of RSSI for varying degrees of RF signal strength applied.
