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 typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Linx DP1203 Series Radio-Only Transceiver
Allows Effective Customization to Optimize
June 14, 2013
— The new DP1203 Series radio-only RF transceiver module is designed for the wireless transmission
of digital data at data rates of up to 152.3 kbps. Operating in the 433, 868 and 915 MHz
license-free ISM (Industrial Scientific and Medical) frequency bands, this module series is
ideal for applications that require full-control of the radio channels and configuration, without
having to go through the effort and expense of a discrete RF design.
The module has a
maximum output power of +15 dBm and a receiver sensitivity of –111 dBm. This gives
the module a typical line of sight range of 2 to 3 miles (3.2 to 4.8 km) at the maximum
output power with typical monopole whip antennas, depending on frequency. 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.
DP1203 Series transceiver module contains all of the components necessary for the radio link,
but is otherwise completely configurable. All of the transceiver configuration registers are
available to optimize the RF link for the application with an external microprocessor through
a 3-wire interface. This allows the designer the ability to optimize the module for their specific
needs. This includes controlling the radio to maximize battery life and optimize communication
protocol. It also includes the ability adjust the radio on the fly to improve the link quality
through Received Signal Strength (RSSI) and Frequency Error Indicator (FEI) features. The DP1203
modules can be used in any environment where wireless remote connection is an advantage. They
are perfect for complex wireless networks involving high speed data rate applications. Application
examples include security systems, home and industrial automation, process, access and building
controls and home appliance interconnections.
Another key feature to the DP1203 family
of modules is simplicity: modules and antennas are the only RF components needed and tuning
is not required. In addition, a simple 3-wire interface is used for configuration, limiting
the number of connections and software overhead.
The DP1203 radio module is suitable
for applications seeking to satisfy the European (ETSI EN300-220-1 and EN301 439-3) or the North
American (FCC part 15.247 and 15.249) regulatory standards.
