Linx's 25 Series RF Transceiver Module Offers Reliable
Bi-Directional Transfer of Digital Data
|
July 3, 2013 — Designed for dependable bi-directional transfer of digital data, the
25 Series RF transceiver module is capable of transmitting over distances of up to 1 mile (1.6 km)
line of sight. Operating in the 902 to 928 MHz ISM (Industrial Scientific and Medical) frequency band, the
module is capable of generating +13 dBm into a 50 ohm load and achieves an outstanding typical sensitivity
of –105 dBm. Regulations in the country of operation dictate the maximum legal output power, so the final system
range may be less depending on the country of operation.
 The
25 Series module implements a Frequency Hopping Spread Spectrum (FHSS) protocol along with networking and assured
delivery features. It has a Universal Asynchronous Receiver Transmitter (UART) serial interface that can be connected
directly to microcontrollers, RS-232, RS-485 converters or USB adaptors. The module automatically handles all radio
functions resulting in a UART-to-antenna wireless link.
The transceiver has a robust built-in protocol. A
Carrier Sense Multiple Access (CSMA) algorithm makes sure the channel is clear before sending data. Networking and
assured delivery enable many system configurations. The transceiver contains several registers, accessed through
the UART, that control its configuration and operation.
Common applications for the 25 Series transceiver
module that require reliable digital date transfer include asset tracking, automated meter reading, wireless sensors
and industrial as well as home automation.
An evaluation module is available that has the module on a board
with an antenna connector and voltage regulator. This module has obtained United States FCC certification and greatly
reduces the expense and time to implement a wireless solution.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
