WiMAX OPERATION
Figure 25 shows a plot of adjacent channel leakage ratio (ACLR)
vs. P
64 QAM, single carrier with a 10 MHz channel bandwidth. This
signal is generated by a WiMAX-enabled source and followed
with suitable band-pass filtering. The band-pass filter helps reduce
the adjacent and alternate channel noise and distortion out of
the signal generator down to −63 dB in the adjacent channels
and −76 dB in the alternate channels at 2.6 GHz and −60 dB
at 3.5 GHz.
Below an output power of 7 dBm, measured ADL5321 output
spectral performance is limited by the signal quality from the
signal source used (−63 dB at 2.6 GHz and −60 dB at 3.5 GHz).
At high power operation, input power to the ADL5321 is 1 dBm
for 15 dBm output power and the source ACLR is −60.2 dB. It is
expected that with a better signal source, the ADL5321 output
spectral quality improves further, especially at output power
levels ≤10 dBm. For instance, the
measured ACLR is −69 dB for an output power of −10 dBm.
For output powers up to 10 dBm rms, the ADL5321 adds very
little distortion to the output spectrum. At 2.6 GHz, the ACLR is
−59 dB and a relative constellation error of −46.6 dB (<0.5% EVM)
at an output power of 10 dBm rms.
