Instruction Manual
Device usage
In order to take advantage of the performances described in the technical specifications and to
comply with the operating conditions which characterize the Certification, the receiver has to be
fitted on a printed circuit, considering what follows:
5 V dc supply:
1. The receiver must be supplied by a very low voltage source, safety protected against short
circuits.
2. Maximum voltage variations allowed: ± 0,25 V.
3.
De-coupling, next to the receiver, by means of a minimum 100.000 pF. ceramic capacitor.
Ground:
1. It must surround at the best the welding area of the receiver. The circuit must be double layer,
with throughout vias to the ground planes, approximately each 15 mm.
2. It must be properly dimensioned, specially in the antenna connection area, in case a radiating
whip antenna is fitted in it (an area of approximately 50 mm radius is suggested.)

Suggested lay-out for the device correct
usage
50 Ohm line:
1. It must be the shortest as possible.
2. 1,8 mm wide for 1 mm thick FR4 printed circuits and 2,9 mm wide for 1,6 mm thick FR4
printed circuits. On the same side, it must be kept 2 mm away from the ground circuit.
3. On the opposite side a ground circuit area must be present.
