MODULE DESCRIPTION
THE SAW-BASED DESIGN ADVANTAGE

figure 1: Overall block Diagram
The RM Series is a SAW-(Surface Acoustic Wave) based double-conversion FM
superheterodyne receiver designed to be utilized in combination with a matching
RM Series transmitter. The receiver utilizes a data slicer that is driven by the AF
output. A carrier detect signal is available to indicate to external circuits that a
signal is present. This signal is extremely useful when implementing duty-cycle
power-save circuits or to indicate to external logic that a signal is being received.
It is internally derived from the degree of noise quieting due to the presence of a
receive carrier. By adding a simple antenna, the pair can transfer serial data at
distances well in excess of 500 feet.The range of any RF link is widely variable
and depends upon many factors, including the type of antenna employed and the
operating environment.The 500 ft. quoted range is a typical operating distance
over open ground using 1/4-whip antennae at both ends of the link at 5 feet
above the ground. Use of a less efficient antenna or adverse environmental
factors such as interference, obstacles, or multipath can substantially reduce the
link’s reliable working range. Slowing the data rate or utilizing a directional
antenna (especially on the receiver) can provide increased performance but may
not comply with licensing requirements. It is recommended that your individual
application be reviewed with Linx prior to entering production or seeking
approvals.
The SAW (Surface Acoustic Wave) device provides a highly accurate frequency
source with excellent immunity to frequency shift due to age or temperature. The
use of a SAW device on both the transmitter and receiver modules allows the
receiver’s pass opening to be quite narrow, resulting in outstanding sensitivity
and greater immunity to interfering signals. As an additional benefit, the SAW
device is manufactured to resonate at a precise frequency, thus eliminating
production tuning and lowering parts count.The SAW device, in combination with
advanced design and manufacturing techniques, has made it possible to reduce
the size and cost of an RF link, while enhancing its performance to a level rivaling
far more complex and costly systems. The end user benefits from improved
product range and reliability and the OEM manufacturer from lower cost and
simpler manufacturing procedures.
