MRX-002S
UHF AM Receiver Module
Description
The MRX-002S 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. Because all tuning is automatic and the
module functions are completely integrated, this module is
both a highly reliable and low cost solution for high volume
wireless applications. An external antenna is the only component
required, therefore the receiver can be easily integrated
into other applications. The MRX-002S contains
two features that are not found in the MRX-002.
The MRX-002S contains a SAW filter and/or a low
noise amplifier, which reduce noise and increase selectivity
and sensitivity. |

The MRX-002S is an enhanced version of the MRX-001 and the MRX-011. Specifically, the MRX-
002S contains both Shutdown and Wakeup features. These features are perfect for low and ultralow
power applications, such as RKE and remote controls. Additionally, post-detection data filtering is
internal to the receiver. Finally, the MRX-002S 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. |
