OPHI and OPLO. The overall gain depends upon the source
and load impedances due to the resistive nature of the input and
output ports.
Digital control of the AD8369 is achieved using either a serial or
a parallel interface. The mode of digital control is selected by
connecting a single pin (SENB) to ground or the positive sup-
ply. Digital control pins can be driven with standard CMOS
logic levels.
The AD8369 may be powered on or off by a logic level applied
to the PWUP pin. For a logic high, the chip powers up rapidly
to its nominal quiescent current of 37 mA at 25ºC. When low,
the total dissipation drops to less than a few milliwatts.
The AD8369 is fabricated on an Analog Devices proprietary, high
performance 25 GHz silicon bipolar IC process and is available
in a 16-lead TSSOP package for the industrial temperature range
of –40
∞C to +85∞C. A populated evaluation board is available.
PRODUCT DESCRIPTION
The AD8369 is a high performance digitally controlled variable
gain amplifier (VGA) for use from low frequencies to a –3 dB
frequency of 600 MHz at all gain codes. The AD8369 delivers
excellent distortion performance: the two-tone, third-order
intermodulation distortion is –69 dBc at 70 MHz for a 1 V p-p
composite output into a 1 k
W load. The AD8369 has a nominal
noise figure of 7 dB when at maximum gain, then increases with
decreasing gain. Output IP3 is +19.5 dBm at 70 MHz into a
1 k
W load and remains fairly constant over the gain range.
The signal input is applied to pins INHI and INLO. Variable gain
is achieved via two methods. The 6 dB gain steps are implemented
using a discrete X-AMP
® structure, in which the input signal is
progressively attenuated by a 200
W R-2R ladder network that
also sets the input impedance; the 3 dB steps are implemented at
the output of the amplifier. This combination provides very
accurate 3 dB gain steps over a span of 45 dB. The output imped-
ance is set by on-chip resistors across the differential output pins,
