Power Supply:
1. TX 434 SMALL IA must be supplied from very low voltage safety source protected against the short
circuits. Maximum voltage variations allowed: 1,8 ÷ 3,6 V. However it is preferable to maintain a stable
voltage to a predetermined value in the range of voltage as specified above, using a "fast transient
response" voltage regulator.
2. Decoupling, close to the transmitter, with a ceramic capacitor of minimum 100nF.
3. Connect electrolytic capacitor 100uF, low ESR, close to pin 2 (+Vcc).
Input pin interface:
Put 100pF capacitor close to the corresponding input pin 3, connected between them and the ground plane.
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.
Antenna:
Embedded Antenna, leave it free from metal materials. Keep at least a 2cm radius free area.
