Applications

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.
