General Description
The T5 and R5 data link modules are miniature
UHF radio modules, which enable the
implementation of a simple telemetry link upto 300
metres, and at data rates of up to 128Kbit/s
The T5 and R5 modules will suit one-to-one and
multi-node wireless links in applications including
building and car security, remote industrial
process monitoring and computer networking.
The ‘B’ derivative parts offer a cost reduced
version.
R5-434
• High sensitivity
• Analogue / Digital Outputs
• Signal strength output (RSSI)
• On board AGC
• Single conversion FM Super-Het
• Double RF filtering (inc saw front end)
The receiver is based on the classical superhet
single conversion architecture utilising a PLL xtal
referenced oscillator which yields a highly stable
IF frequency (10.7 MHz). This hence allows use of
high Q bandpass filters offering excellent adjacent
channel rejection and hence high interference
Immunity.
Because of its small size and low power
requirements, these modules are ideal for use in
portable battery powered wireless applications.

4. The data slicer is optimised for a 50:50 duty cycle, hence for reliable communications data should be
encoded using a suitable scheme such as Manchester Encoding, though pulse width modulation up to
30:70/70:30 can also be utilised.
