RADIO MODULE MRX-005S UHF AM RECEIVER MODULE Y R A IN M I L E PR DATA SHEET Radios, Inc. May 29, 2007 Preliminary Data Sheet MRX-005S UHF AM RECEIVER MODULE The MRX-005S is an on-off keyed (OOK) high performance, ultra compact receiver operating at the 902-928 MHz band. This integrated modularized receiver is primarily intended for use in part 15.231 and 15.249 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-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. Y R A IN M I L Typical Applications E PR 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. Postdetection 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.

Note 1: Sensitivity is defined as the average signal level measured at the input necessary to achieve 10e-2 Bit Error Rate (BER). The input signal is defined as a return-to-zero (RZ) waveform with 50% average duty cycle at a data rate of 2400bps. The RF input is assumed to be matched into 50 ohms. Note 2: Spurious reverse isolation represents the spurious components which appear on the RF input (ANT) pin measured into 50 ohms with an input RF matching network. Note 3: Sensitivity, a commonly specified Receiver parameter, provides an indication of the Receiver’s input referred noise, generally input thermal noise. However, it is possible for a more sensitive receiver to exhibit range performance no better than that of a less sensitive receiver, if the “ether” noise is appreciably higher than the thermal noise. “Ether” noise refers to other interfering “noise” sources, such as FM radio stations, pagers, etc. A better indicator of receiver range performance is usually given by its Selectivity, often stated as Intermediate Frequency (IF) or Radio Frequency (RF) bandwidth, depending on receiver topology. Selectivity is a measure of he rejection by the receiver of “ether” noise. More selective receivers will almost invariably provide better range. Only when the receiver selectivity is so high that most of the noise on the receiver input is actually thermal will the receiver demonstrate sensitivity-limited performance.

Compliance: Embedded wireless modules are intended for use as component devices which require peripheral elements to operate. Radios, Inc.’s modules are intended to be used in products requiring compliance. They are, however, not pre-approved by the FCC or any other agency worldwide unless so stated. The user or customer understands that regulatory compliance may be required prior to the sale or operation of the module or development system, and agrees to abide by all laws governing the module’s or development system’s use in the country of operation. The approval process of embedded wireless modules in the United States is relatively uncomplicated. The Federal Communications Commission (FCC) is the governing body in the US that specifies its requirements in the Code of Federal Regulations (CFR), Title 47. Title 47 consists of several volumes and it is necessary to first identify the correct section that applies to your application. These rules require that a device which intentionally creates RF emissions be FCC compliant; i.e., pre-tested for compliance and assigned an identification number. Radios, Inc. offers pre-screening at one of our affiliate test sites. Final certification is then accomplished by an independent test laboratory. After passing compliance testing, you will be issued a unique ID number which must be placed on each product manufactured. Any questions dealing with interpretations of the rules relating to testing or compliance should be addressed to: FCC Equipment Authorization Division Customer Service Branch, MN 1300F2 7435 Oakland Mills Road Columbia, MD 21046 -Page 7- MRX-005S UHF AM RECEIVER MODULE Returns: Products may be returned directly to Radios, Inc. for evaluation.
