MRX-009S
UHF AM Receiver Module
Description
The MRX-009S is an on-off keyed (OOK) high performance,
ultra compact, long range receiver for remote wireless
applications. The receiver operates at 315, 390, 418, and 433
MHz, and is primarily intended for use in part 15.231 systems.
The MRX-009S is an enhanced version of other MRX receivers
with key performance upgrades such as higher sensitivity
(typically 6dB higher than the MRX-002) and faster recovery
from Shutdown (typically 1ms). Because an external antenna is
the only component required, the receiver can be easily integrated
with other applications. The MRX-009S operates at
low power consumption, generates low harmonic emissions and
is a highly reliable wireless link. The MRX-009S is a well
designed receiver suitable for a variety of RF applications, particularly
high volume OEM applications. |

The MRX-009S contains two features that are not found in the MRX-009. The MRX-009S
contains a SAW filter and/or a low noise amplifier, which reduce noise and increase selectivity and sensitivity.
The MRX-009S has post-detection data filtering internal to the receiver. Additionally, one of
two filter bandwidths may be selected externally by the user. The MRX-009S comes in two versions:
fixed-mode (FX), which functions as a conventional, superhet receiver and increases selectivity and sensitivity
performance, and sweep mode (SWP), which sweeps a wider RF spectrum and allows the receiver
to be used with low cost, LC transmitters. |
