based software WinQSIM via a GPIB interface. The AMIQ generator has a pseudo random binary
sequence (PRBS) generator and a bit error test set built in. The resulting I/Q signals are applied to
the SMIQ to generate a ASK (OOK) spectrum at the desired RF frequency.
Data is demodulated by the TDA5251 and then sent back to the AMIQ to be compared with the
originally sent data. The bit error rate is calculated by the bit error rate equipment inside the AMIQ.
Baseband coding in the form of Manchester is applied to the I signal as can be seen in the
subsequent figure.

BER Test Setup
In the following figures the RF power level shown is the average power level.
These investigations have been made on an Infineon evaluation board using a data rate of 4 kBit/
s with manchester encoding and a data filter bandwidth of 7 kHz. This is the standard configuration
of our evaluation boards. All these measurements have been performed with several evaluation
boards, so that production scattering and component tolerances are already included in these
results.
Regarding the data filter bandwidth it has to be mentioned that a data rate of 4 kBit/s using
manchester encoding results in a data frequency of 2 kHz to 4 kHz depending on the occurring
data pattern. The test pattern given by the AMIQ is a pseudo random binary sequency (PRBS9)
with a 9 bit shift register. This pattern varies the resulting data frequency up to 4 kHz.
