Application Circuits
FOUR-QUADRANT MULTIPLIER
Applications requiring multiplication, squaring or other non-
linear functions can be implemented with four-quadrant mul-
tipliers. The LMH6503 implements a four-quadrant multiplier
as illustrated in
Figure 11
:
FREQUENCY SHAPING

LMH6503 can be accomplished using parallel networks con-
nected across the R
ports. The network shown in the

ORDER TUNABLE BANDPASS FILTER
The LMH6503 Variable-Gain Amplifier placed into a feed-
back loop provides signal processing function such as in a
2nd order tunable bandpass filter. The center frequency of
the 2nd order bandpass shown in
Figure 13
is adjusted
through the use of the LMH6503’s gain control voltage, V
.
The integrators implemented with two sections of a
LMH6682, provide the coefficients for the transfer function.
