Tank circuit LF antenna

13 April 2011 Telecoms, Datacoms, Wireless, IoT

Premo Group has launched a new DCF and ripple control antenna for applications using atomic watch signals.

There are several clock signal transmitters covering different zones around the world. These long wave transmitters use FSK modulation with frequency precision of ±107 Hz and signal speed of 200 Bd. The though-hole RCA-THT antenna can be set and tuned in different frequencies from 40 kHz to 139 kHz, for clock applications and power control and management applications (tariff switching and load management), lighting controls, smart metering, etc.

The antenna is shipped already tuned to the resonant frequency specified. The fine tuning process is done in the PREMO production line by an automatic station which checks the antenna in real-time, achieving a high precision in the centre frequency. These antennas are configured as L-C resonant parallel tanks which offer a high resistance (more than 75 kΩ) at resonance frequency.
