No IFs about it: transceiver prolongs battery life
Available now from Low Power Radio Solutions is the latest transceiver from Circuit Design.
Despite its low cost, the LX2400 has all the benefits of spread spectrum technology originally developed to enhance the security and reliability of military communications systems.
Its frequency hopping spread spectrum (FHSS) technology causes it to transmit data on one frequency then rapidly hop to another frequency.
Should interference occur, the data are resent on another frequency.

Long-range transceiver has split personality
Available from LPRS, the RDT868 transceiver has a novel construction which makes it both a highly reliable transceiver and a novel solution for sending high volumes of data over long distances.
Additional benefits to OEMs include extended transmission range and increased datarates.
While spread spectrum has been used for decades, the cost of such solutions has been expensive, typically hundreds of pounds.
AeroComm's contribution is the culmination of a multi-year design effort to provide FHSS technology at mass-market prices.
The ConnexRF line addresses the full range of OEM customer requirements: small size (1.65in x 2.65in x 0.2in, including antenna), simple integration (5V TTL serial data I/O), efficient data throughput (up to 56Kbit/s), long range (up to 150m) and low power consumption (less than 100mA average current draw).
The LX2400 is a complete RF module including antenna.
All frequency hopping, synchronisation and RF system data transmission/reception is performed by the LX.
When compared to integrating an RF chipset, the LX speeds time to market, reduces R and D costs and increases likelihood of success.
The transceivers include useful features typically found only on expensive radios including RSSI (receive signal strength indication) and an in-range indicator confirming a good RF link.
The LX2400 employs AeroComm's proprietary ConnexSync technology, which optimises data throughput and reduces component cost.
ConnexSync allows LX2400 radios to find other radios quickly, establish and maintain synchronisation and minimise RF "overhead" time for hopping.
Custom algorithms enable the radios to scan and locate each other in one-third the time typically required.
As a result, high datarates and very low latency are achieved, making the LX very responsive for control applications.
Users can configure the radios on unique channels, enabling independent, collocated networks.
Point-to-point and point-to-multipoint networks are supported.
The LX2400 is ideal for large volume applications requiring highly reliable communication (even in industrial settings) with superior cost efficiency.
Examples include handheld terminals, security systems, remote controls, lighting control, electronic signs and consumer electronics.
Developer kits are available now exclusively from LPRS.
These include everything necessary for customer evaluation and integration. Request a free brochure from Low Power Radio Solutions ...
