Circuit Design releases radio modules

The modules are designed for embedding in industrial equipment.

They include nearly all the parts necessary for radio transmission in a small and robust shielding case.

With narrow-band FSK modulation, the modules are very resistant to noise.

The receiver also has high receive sensitivity, offering stable operation even in weak electric fields.

The modules achieve a line-of-sight communication distance of more than 600m with only 10mW power.

While the modules are small, they feature high-frequency characteristics that give high reliability, as well as resistance to mechanical vibration and shock.

The US model (457MHz) and European model (434MHz) are pin-compatible, enabling users to develop products for both American and European markets with a common interface.

The equipment has received wireless authorisation, obtaining CE authorisation for the European model and FCC authorisation for the US model (Transmitter: FCC Part 90 equipment authorisation).

Radio frequency can be selected from 32 pre-programmed channels in 25kHz steps, or by setting an arbitrary frequency channel.

The modules can operate in temperatures from -20C to +60C, and are suitable for indoor and outdoor use.

With strong blocking performance and selectivity, the modules offer stable operation even in high-noise environments.

A license is required for use in the USA.
