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.
