The declared technical features have been obtained by applying the following testing system:
Picture 1: Measurement of sensitivity
Device usage
In order to obtain the performances described in the technical specifications and to comply with the
operating conditions, which characterize the Certification, the transmitter has to be mounted on a printed
circuit taking into account the following.
Power Supply:
1. RX-8MR50++ must be supplied from very low voltage safety source protected against the short circuits.
Maximum voltage variations allowed: 3 ÷ 5,5 V. However it is preferable to maintain a stable voltage to a
predetermined value in the range of voltage as specified above, using a linear voltage regulator.
2. Connect electrolytic capacitor 100uF, low ESR, close to pin 15 (+Vcc).
Ground:
The ground must surround at the best the welding area of the module and must also be realized in the
lower face of the PCB in order to obtain the optimal result, with the through holes connecting the two
ground planes approximately each 15 mm.
It must be properly dimensioned, especially in the antenna connection area, in case a radiating whip
antenna is fitted in it (an area of approximately 50 mm radius is suggested).

Picture 2: Suggested lay-out for the device correct usage
Antenna:
1. A whip antenna, 8cm long and approximately 1mm diameter, brass or copper wire made, must be
connected to the RF input of the receiver (pin 3).
2. The antenna body must be keep straight as much as possible and it must be free from other circuits or
metal parts (5cm minimum suggested distance).
3. It can be utilized either vertically or horizontally, provided that a good ground plane surrounds the
connection point between antenna and transmitter output.
50 Ohm line:
1. It must be the shortest as possible.
2. 1,8mm wide for 1mm thick FR4 printed circuits and 2,9mm wide for 1,6mm thick FR4 printed circuits.
On the same side, it must be kept 2mm away from the ground circuit.
3. On the opposite side a ground circuit area must be present.
Antenna connection:
1. It may be utilized as the direct connection point for the radiating whip antenna.
2. It can bear the connection of the central wire of a 50Ω coaxial cable. Be sure that the braid is welded to
the ground in a close point.
N.B.: As an alternative to the a.m. antenna it is possible to utilize the whip model manufactured by Aurel
(see related Data Sheet and Application Notes).
By fitting whips too different from the described ones, the EEC Certification is not assured.
Other components:
1. Keep the receiver separate from all other components of the circuit (more than 5mm).
2. Keep particularly far away and shielded all microprocessors and their clock circuits.
3. Do not fit components around the 50Ω line. At least keep them at 5mm distance.
If the antenna connection is directly used for a radiating whip connection, keep at least a 5cm radius free
area. In case of coaxial cable connection 5mm radius will suffice.
