MRX-005S
UHF AM RECEIVER MODULE
The MRX-005S is an on-off keyed (OOK) high perfor-
mance, ultra compact receiver operating at the 902-928
MHz band. This integrated modularized receiver is pri-
marily intended for use in part 15.231 and 15.249 sys-
tems. Because all tuning is automatic and the module func-
tions are completely integrated, this module is both a
highly reliable and low cost solution for high volume wire-
less applications. An external antenna is the only compo-
nent required, therefore the receiver can be easily inte-
grated into other applications. The MRX-005S contains
two features that are not found in the MRX-005. The MRX-005S contains a SAW filter and/or a low
noise amplifier, which reduce noise and increase sensitivity and selectivity.
The MRX-005S offers a transit standby mode and a shutdown mode. These features make the
MRX-005S perfect for power applications in both one-way and bi-directional wireless links. Post-
detection data filtering is internal to the receiver, and normal filter bandwidth is fixed at 300kHz. The
MRX-005S is a well-designed receiver suitable for a variety of RF applications.
