ISM 433 MHz ASK Transmitter – Preliminary Data Sheet

AS3902

Figure 9:

Modulation bandwidth of the AS3902 at 16 kbit/s, measured close to the ETSI

EN 300 220-1 recommendation for wide-band equipment, clause 8.6. (Only difference:

5 kHz VBW was used instead of 10 kHz). From EN 300 220-1 the modulation bandwidth

is defined to be the frequency difference between the points wherein the power level is

above -36 dBm. Therefore the bandwidth value is dependent on the E.I.R.P. and should

be within the ISM band limits. The marker settings correspond to the limits of the

433 MHz ISM band.
