Xemics Launches New Drop-In Transceiver Module

Neuchâtel, Switzerland -- Xemics has just released a DP1205 'drop-in' module operating in the unlicensed 433 MHz, 868 MHz, and 915 MHz bands. The DP1205 module is based on the XE1205 transceiver and offers a simple, cost-effective way to make any wired application wireless.

Using the module is as simple as connecting it to an SPI-bus enabled microcontroller and adding an antenna. The module is fully tested and ETSI/FCC pre-certified and can operate out of the box with simple configuration.

Although the module is very simple to use, it still offers excellent performance and flexibility. With a 128 dB link budget (4.8 kbit/s, 0.1% BER), a pair of modules can communicate over distances in excess of several hundred meters. Some customers have reported in excess of several kilometers line-of-sight. Other key specifications are 15 dBm transmit power, 152.34 kbit/s maximum RF data rate, 14 mA receive and 45 mA transmit typical current consumption.

"The DP1205 enables customers to rapidly develop and deploy high-efficiency narrowband ISM solutions," Rob Whittaker, Xemics' business unit manager ISM wireless, stated. "The DP1205 module is a high-performance choice for customers wishing to RF-enable their products."

New features in the DP1205 include a 16-byte FIFO data buffer, an SPI-bus data link, and an enhanced AFC algorithm, all of which contribute to reduced host-controller overhead and thereby lower system cost.

The DP1205 module fully meets the requirements for 25 kHz channel spacing and adjacent channel power of less than -37 dBm and is ideal for applications operating in the 433-868-915 MHz band, such as alarms, security, automatic metering, services, and controls.

The modules are available in a surface-mount, manufacturing-friendly package that supports automated assembly and IR reflow. The overall dimensions of the module are 18.5 mm wide by 30.5 mm long.
