Description
The QFMT6 AND QFMR6 miniature UHF radio
modules enable the implementation of a reliable
telemetry link at data rates of up to 64 Kbits/s.
The QFMT6 is based on a classical phase lock loop
using a crystal reference oscillator. This results in an
accurately controlled RF output in the frequency
domain. A significant advantage of this is that narrow
filtering can then be used in the receiver, which
results in high interference immunity.
In addition, the modules are fitted with an on-board
voltage regulator which enhances performance from
improved supply filtering and also ensures a constant
RF output level.
The QFMR6 is based on the single conversion
superhet principle utilising a crystal based phase lock
loop for accurate generation of the local oscillator.
This allows use of high Q bandpass filters resulting in
good adjacent channel selectivity and high
interference immunity.
The QFMT6 and QFMR6 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.
Because of its small size and low power
requirements, these modules are ideal for use in
portable battery powered wireless applications.
These modules may be used within areas of high
interference, or ‘radio traffic’. Due to the design, they
provide a highly reliable radio link.
