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 at several frequency options, these modules have been designed to provide a reliable wire free link within the presence of other interference at the same frequency, 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 DS2010_2 Dec ‘01 ©2001 REG No 277 4001, England.
