DECT brings advantages to data-telemetry systems
The first DECT system from LPRS combines the established DECT networking protocol with small size, high data throughput, low power consumption and simplicity
The new device combines a quadrature modulated transmitter with a direct conversion receiver.
The received signal is directly down-converted to baseband, thereby eliminating the need for any intermediate frequency circuitry.
Not only does this architecture reduce power consumption over competing designs, it also improves the switch-over time between transmission and reception, as well as providing high stability in the RF circuitry.
The STD-403 can operate on eight channels in the 434MHz band, with sustained datarates up to 19.2Kbit/s (maximum 56Kbit/s), and so is ideal for applications requiring medium-speed two-way communication, such as industrial remote controls with feedback and bidirectional data telemetry.
Measuring just 50 x 30 x 7mm, the module has a wide operating voltage range from 2.7 to 12V, and typically consumes only 36mA while transmitting and 24mA when receiving, making it suitable for portable battery-powered applications such as credit-card swipe units.
