Remote control transmitters need no licence
RF Solutions has launched a series of rugged, licence-exempt hand-held radio transmitter encoders for remote control applications designed to operate in harsh and outdoor environments
The modules are able to achieve datarates up to 20Kbit/s when used in a simple telemetry link.
The transmitter design uses a PLL-stabilised crystal oscillator to give an accurately controlled RF output, permitting the use of narrow filtering on the receiver side.
The receiver itself is based on the single conversion superhet principle, again using phase locked loop technology.
The overall result is a narrowband licence-exempt product with a range of approximately 600m.
Fully shielded miniature SIL packages house both the transmitter and receiver modules.
The dimensions of the packages are just 31 x 10 x 3.5mm and 49 x 17 x 4mm, respectively.
A wide operating temperature range of -25 to +55C for the transmitter, and -10 to +55C for the receiver, helps the T7/R7 to achieve a high degree of stability in a diverse range of designs.
An option for a -40 to +80C rated receiver is also available.
The transmitter is able to operate from a supply voltage ranging from 2.2 to 10V DC.
Coupled with a small current consumption of 6mA, this gives a very low overall power consumption figure, making the module ideal for use in battery powered wireless applications.
The T7/R7 narrowband module range is EN 300-220 compliant.
