RCA-SMD - Radio Clock Receiver Antenna SMD

Documentation détaillée
Description
This component (RCA-SMD series) is the first radio clockW receiver antenna in SMD technology in the market for time signalW receiver applications.

The component is supplied in tape and reel, ready to use in automatic pick and place SMT machines. In a time signal receiver circuit, the antenna is the biggest component used, PREMO has miniaturized it enough (75mm x 15mm x 6.3mm) to develop low profiles PCB's with 100% integration level, avoiding flying wires or manual assemblies in the complete process.

There are several clock signal transmitters in different countries: DCF77-77.5kHz (Germany), HBG-75kHz (Switzerland), MSF-60kHz (United Kingdom), TDF-162kHz (France), JJY-40&60kHz (Japan), WWVB-60kHz (USA).

Standard SMD version of this radio clock antenna at 40, 60 and 77.5 kHz are available. The component is configured as L-C resonant parallel tank (RCA-SMD-77A: 1.3mH // 3.3nF for 77.5 kHz and RCA-SMD-60A: 2.1mH // 3.3nF for 60 kHz) which offer a higher resistance (more than 75 kOhms) at resonance frequency (+/- 0.2 kHz).

The antenna is shipped already tuned to the resonant frequency specified. The fine tuning process is done in the PREMO production line by a high reliable automatic station. This station check the antenna in real-time, achieving a high precision in the center frequency tuned.
