Device usage
In order to obtain the perfor ances described in the technical specifications and to co ply with the
operating conditions, which characterize the Certification, the trans itter has to be ounted on a printed
circuit taking into account the following.
Power Supply:
1. RX-4MR50-SMD ust be supplied fro very low voltage safety source protected against the short circuits.
Maxi u voltage variations allowed: 3 ÷ 5,5 V. However it is preferable to aintain a stable voltage to a
predeter ined value in the range of voltage as specified above, using a "fast transient response" voltage
regulator.
2. Connect electrolytic capacitor 100uF, low ESR, close to pin 2 (+Vcc).
Ground:
The ground ust surround at the best the welding area of the odule and ust also be realized in the
lower face of the PCB in order to obtain the opti al result, with the through holes connecting the two
ground planes approxi ately each 15 .
It ust be properly di ensioned, especially in the antenna connection area, in case a radiating whip
antenna is fitted in it (an area of approxi ately 50 radius is suggested).
Antenna:
1. A whip antenna, 16,5 long and approxi ately 1 dia, brass or copper wire ade, ust be
connected to the RF input of the receiver (pin 6).
2. The antenna body ust be keep straight as uch as possible and it ust be free fro other circuits or
etal parts (5c ini u suggested distance).
3. It can be utilized either vertically or horizontally, provided that a good ground plane surrounds the
connection point between antenna and trans itter output.
50 Ohm line:
1. It ust be the shortest as possible.
2. 1,8 wide for 1 thick FR4 printed circuits and 2,9 wide for 1,6 thick FR4 printed circuits.
On the sa e side, it ust be kept 2 away fro the ground circuit.
3. On the opposite side a ground circuit area ust be present.

Antenna connection:
1. It ay 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. . antenna it is possible to utilize the whip odel anufactured by Aurel
(see related Data Sheet and Application Notes).
By fitting whips too different fro the described ones, the EEC Certification is not assured.
Other components:
1. Keep the receiver separate fro all other co ponents of the circuit ( ore than 5 ).
2. Keep particularly far away and shielded all icroprocessors and their clock circuits.
3. Do not fit co ponents around the 50Ω line. At least keep the at 5 distance.
If the antenna connection is directly used for a radiating whip connection, keep at least a 5c radius free
area. In case of coaxial cable connection 5 radius will suffice.
Soldering and assembling layout SMD
Picture : Reco ended layout for Host board
In order to ensure the correct asse bly of the odule you are required to apply a production process
observing carefully the following reco endations:
Soldering paste: Use soldering paste as SAC305 (96,5% Sn, 3% Ag, 0,5% Cu), with a thickness> 150u .
Asse bly: the odule can be asse bled with auto atic achine by using a suction cup tool, applied on
bigger integrated circuit

Soldering: the odule can be soldered on host board, through a reflow profile for Lead-free co ponents.
Jedec standard “J-STD-020E”
Standard Jedec “J-STD-020E” defines te peratures and exposure ti es, is attached below graph and profile
table ti e / te perature reco ended for the purpose.
For host that provide ore reflow cycles it is reco ended to perfor the soldering of the odule at the
end of the soldering cycle, taking care to li it excessive vibrations during the ter inal phase of reflow
soldering paste.
