General Description
The TRA150D radio transceiver module was designed to provide reliable wireless operation
at moderate data rates for use throughout the world.
The TRA150D is a low power ASK transceiver that has been designed to interface directly to
a micro controller.
The module has been optimised for fast turn on and exhibits a power down mode for low
current operation.
In conjunction with a high performance antenna, the unit has a typical range up to several km.
The module is compatible with our WDXX range of controllers for evaluation, development
and turnkey solutions.
The receiver section uses a single conversion super-het design,

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 achieve with a ground independent, 3dB or better gain, ground-
independent antenna.
Good range can be achieved with either a straight piece of wire, rod or PCB track @
¼ wavelength (500mm). Further range may be achieved if the ¼ wave antenna is
placed perpendicular in the middle of a solid earth plane measuring at least 500mm
radius. In this case, the antenna should be connected to the module via some 50 Ohm
characteristic impedance coax
