General Description
The T7/R7 series are miniature narrow band
transmitter and receiver UHF radio modules,
which enable the implementation of a simple
telemetry link at data rates up to 20Kbits/s.
These narrow band UHF radio modules provide a
very high RF performance for general purpose
applications.
The transmitter modules have a power output of
up to 25mW. When combined with a very high
receiver sensitivity these modules obtain a very
high performance of range and reliability within
the 433MHz band.
Available for operation between 433.075 and
434.725 MHz in 25KHz steps there are currently 3
different frequency channels available from stock.
(others available to special order)
The T7G and R7G genesis modules represent the
latest generation of narrow band transmitters.
They retain the same industry standard footprints
and are fully compatible with the T7 and R7
modules to enable incorporation into both new
and existing designs. The improved sensitivity of
the R7G enables a range of up to 1Km when used
with the T7G modules.
