Smart Com Radio Transceiver IC
RF600T
Smart Radio Evaluation Kit
The Smart Radio Evaluation Kit provides a hardware platform to enable
fast development of Radio applications.
Supplied as a pair of boards, each can accept a variety of RF Modules
including transmitters, receivers and transceivers, an RS232 port is
incorporated for direct connection to a PC.
The boards may be used for a wide range of tasks from simple RS232
data transmission to integrated system development and is the ideal
platform for exploring the advantages of using the “Smart Comms” range
of ICs and radio modules.
This eliminates the need to construct hand-wired prototype boards, which
are rarely successful in creating a valid environment for the development
of radio systems. (prototyping board also contains large stray capacitance
values which has a detrimental effect on the RF connections).

Achieving Optimum Range
Range is dependant on many factors including
1. RF Power output
2. Receiver sensitivity
3. Antenna efficiency
4. Local environmental conditions and any local Interference
5. Data Type which is being transmitted.
Whilst items 1-4 are dependant on the system hardware design, item ‘5’ is equally important and often
overlooked. Given that there is a legal maximum power output which can be transmitted, and a limit on the
sensitivity of the receiver (usually constrained by cost), and that the antenna can never achieve 0dB loss
(100% efficiency), then the data structure and coding is an important aspect of the design.
The RF600T uses a fully balanced Manchester encoded data protocol designed for optimum use of the
radio transmission path. Manchester encoding enables the receiver ‘data slicer’ to maintain efficiency for
the duration of the data packet, (unlike many other encoder/decoder systems) which results in reduced bit
errors and therefore ensures maximum range.
