APPLICATIONS
DIRECT CONVERSION MODULATOR
Direct conversion architectures are increasingly being used to
implement base station transmitters. Figure 17 shows how ADI
parts can be used to implement such a system.
The circuit block diagram shows the AD9761 TxDAC being
used with the AD8349. The use of dual integrated DACs, such
as the AD9761 with its specified ±0.02 dB and ±0.004 dB gain
and offset matching characteristics, ensures minimum error
contribution (over temperature) from this portion of the
signal chain.
The local oscillator is implemented using the ADF4360-4. The
low-pass filter was designed using ADIsimPLL for a channel
spacing of 200 kHz and an open-loop bandwidth of 10 kHz.
The LO ports of the AD8349 can be driven differentially from
the complementary RFOUTA and RFOUTB outputs of the
ADF4360-4. This gives better performance than a single-ended
LO driver and eliminates the often necessary use of a balun to
convert from a single-ended LO input to the more desirable
differential LO inputs for the AD8349. The typical
rms phase noise (100 Hz to 100 kHz) of the LO in this
configuration is 1.09°.
The AD8349 accepts LO drive levels from 10 dBm to 0 dBm.
The optimum LO power can be software programmed on the
ADF4360-4, which allows levels from 13 dBm to 4 dBm from
each output.
The RF output is designed to drive a 50 Ω load but must be ac-
coupled, as shown in Figure 17. If the I and Q inputs are driven
in quadrature by 2 V p-p signals, the resulting output power
from the modulator is approximately 2 dBm.
