MRX-009
UHF AM Receiver Module
Description
The MRX-009 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-009 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-009 operates at low power consumption, generates
low harmonic emissions and is a highly reliable wireless link. |

The MRX-009 has post-detection data filtering internal to the receiver. Additionally, one of two filter
bandwidths may be selected externally by the user. The MRX-009 comes in two versions: fixed-mode
(FIX), which functions as a conventional, superhet receiver and increases selectivity and sensitivity, and
sweep mode (SWP), which sweeps a wider RF spectrum and allows the receiver to be used with low cost,
LC transmitters. The MRX-009 is a well designed receiver suitable for a variety of RF applications,
particularly high volume OEM applications. |
