MXR-505
UHF FM TRANSCEIVER MODULE
The MXR-505 is a frequency shift keyed (FSK) high performance,
ultra compact, long range transceiver operating at the 902-928
MHz and 868.25 MHz bands. This integrated modularized trans-
ceiver is designed for use in half-duplex, bidirectional RF links.
The multi-channeled MXR-505 is intended for use in UHF radio
equipment in compliance with both the NorthAmerican Federal
Communications Commission (FCC) part 15.247 and 15.249 sys-
tems and the European Telecommunications Standard Institute
(ETS) specification EN300 200.
The transmitter is composed of both a PLLfrequency synthesizer and a power amplifier. The synthesizer
uses a voltage-controlled crystal oscillator, a dual-modulus prescaler, programmable frequency dividers,
and a phase-detector. The power amplifier’s output power can be programmed to seven different levels.
The MXR-505 has zero IF architecture which enables channel filtering with low-power, integrated low-
pass filters. Each channel includes a pre-amplifier and a third order Sallen-Key RC low-pass filter that
protects the switched-capacitor filter from strong adjacent channel signals. The main channel filter is a
switched-capacitor implementation of a six-pole elliptic low pass filter. The cutoff frequency of the
Sallen-Key RC filter can be programmed to four different frequencies: 100kHz, 150 kHz, 230 kHz, and
340 kHz. Areceive signal strength indicator circuit indicates the received signal level. The MXR-505 is
a well-designed transceiver suitable for a variety of RF applications, particularly voice applications and
high volume OEM applications.

MXR-505
UHF FM TRANSCEIVER MODULE
MXR-505 Communication
Communication with the MXR-505 is accomplished through a universal asynchronous receive/
transmit (UART) peripheral interface. The UART uses 8-bit, non-parity, LSB, 1200bps baud
format. The maximum number of data bytes that can be transmitted or received in one packet is 50.
The user will transmit data through the UART on the MXR-505 via pin 24, URXD. The MXR-505
will packetize and wirelessly transmit the data. Once the data is received on the other side, the
MXR-505 will demodulate the data and send the received data out to the user via pin 23, UTXD.
The data being sent through the UART should follow a specific protocol.
The communication protocol is outlined below:
Byte #1
Number of Bytes – The number of bytes is one byte containing the total number of
data bytes. This byte should not be included in the number of bytes. Therefore, the
number of bytes should be one less than the total number of bytes being sent or
received. The maximum number of data bytes that can be transmitted or received is
50; therefore, the number of bytes should not exceed 50.
Bytes #2-51 Data Bytes – The data bytes are the actual data byte values being transmitted or
received by the MXR-505. The MXR-505 can send or receive a maximum of 50
data bytes per packet. The first two bytes are used as preamble bytes by Radios,
Inc. to differentiate the detection of data from noise. They can be set to any value,
but to work with the HHDS-MLthey must be set to 0xFF and 0x00, respectively.
When the first byte is received through the UART on the MXR-505, the user will have one second
to send the remaining data bytes to the MXR-505. If the MXR-505 does not receive all of the data
bytes within that second, the data the MXR-505 did receive will be dumped. For example, if the
user sends a 10 for the number of bytes and then only sends five more bytes within one second, the
MXR-505 assumes this is corrupted data and does not transmit the packet. The five bytes the
MXR-505 did receive will be discarded and the MXR-505 will wait for a new packet of data to be
received.

resources necessary to assist them with their product development. All technical support is
provided free of charge. Customers have several options to obtain assistance. First, any
questions or concerns can be e-mailed to Radios, Inc. at information@radiosinc.com. We monitor
our e-mail daily, and will respond to all questions promptly. Additionally, to speak directly to a
technical support representative, customers can call Radios, Inc. at 920-564-6622.
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:
