Note1: Values have been obtained by applying the test system shown in Fig. 1 and maximum 5,5 V power supply.

Note2: The minimum and maximum showed values are determined by the device’s construction tolerance.

To define the working frequency of the device, add to these values the deviation caused by the thermal variations (see fig. 3).

Note3: To keep the parameters within the limits established by the rules in force, (see para. “Reference Rules”), it is recommended to

supply the circuit with not more than 5,5V and to comply with all the recommendations specified in para “Device usage”.

Messrs AUR°EL declines all responsibilities in case the a.m. recommendations are disregarded.

The declared technical features have been obtained by applying the following testing system:

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, and keep into consideration what follows:

5V dc supply

1. The transmitter must be supplied by a very low voltage source, safely protected against short circuits.

2. Maximum voltage variations allowed: ± 0,5 V.

3. De-coupling, next to the transmitter, by means of a minimum 100.000 pF ceramic capacitor.

Ground

1. It must surround at the best the welding area of the transmitter. The circuit must be double layer, with

throughout vias to the ground planes, approximately each 15 mm.

2. 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).

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.

It must be kept 2 mm away from the ground circuit on the same side.

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 50 Ω coaxial cable. Be sure that the braid is welded to

the ground in a close point.

Antenna

1. A whip antenna, 16,5 mm long and approximately 1 mm dia, brass or copper wire made, must be

connected to the RF output of the transmitter (pin 11), (see fig. 2).

2. The antenna body must be keep straight as much as possible and it must be free from other circuits or

metal parts (5 cm 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.

N.B: As an alternative to the a.m. antenna it is possible to fit the whip model manufactured by

AUR°EL (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 transmitter separate from all other components of the circuit (more than 5 mm).
