MODULE DESCRIPTION
The RXM-***-ES module is a single-channel receiver designed for the wireless
reception of digital or analog information over distances of up to 1,000 feet
outdoors and up to 500 feet indoors. It is based on a high-performance,
synthesized, single conversion, superhet architecture. FM / FSK modulation and
SAW filtering are utilized to provide performance and noise immunity that are
superior to AM-based solutions. The ES series is incredibly compact and cost-
effective when compared with other FM / FSK devices. Best of all, it is packed
with many useful features, offering a great deal of design flexibility.

THEORY OF OPERATION
The receiver operates in a single conversion superhet configuration, with an IF
of 10.7MHz and a baseband analog bandwidth of 28kHz. It is capable of
receiving a signal as low as -97dBm (typical). The signal is filtered at the front
end by a SAW band-pass filter. The filtered signal is then amplified and down-
converted to the 10.7MHz IF by mixing it with a LO frequency generated by a
PLL-locked VCO. The 10.7MHz IF is then amplified and filtered. Finally, a PLL
demodulator is used to recover the baseband analog signal from the carrier. This
analog signal is low-pass filtered and then output on the AUDIO line.
The analog output can be individual frequencies or complex waveforms, such as
voice or music. The AUDIO line can also be used to recover unsquared data in
instances where a designer wishes to use an external data slicer.
The ES receiver also features a high-performance on-board data slicer for
recovery of data transmission. Its output is internally derived from the filtered
analog baseband, which is squared and made externally available on the DATA
line. The data slicer is capable of recreating squared waveforms from 100Hz to
28kHz, giving a data rate bandwidth of 200bps to 56kbps.
It is important to note that this receiver does not provide hysteresis or squelching
of the DATA line. This means that in the absence of a valid transmission or
transitional data, the DATA line will switch randomly. The effects of this noise
must be considered and will be discussed in further detail later in this guide.
The receiver features a Received Signal Strength Indicator (RSSI) output. The
RSSI pin outputs a linear voltage relative to the incoming signal level. This output
has many valuable uses, including interference assessment, signal strength
indication, external data squelching and qualification, and transmitter presence
indication. Since RSSI values vary from part to part and correspond to signal
strength and not necessarily distance, it is not recommended for range-finding
applications.
