Linear Equivalent Circuit
In order to predict the performance of the HMPP-386x
as a switch or an attenuator, it is necessary to construct a
model which can then be used in one of the several linear
analysis programs presently on the market. Such a model
is given in Figure 16, where R
c
will reveal the fact that the package parasitics (inductance
and capacitance) are much lower for the MiniPak than they
are for leaded plastic packages such as the SOT-23, SOT-
323 or others. This will permit the HMPP-386x family to be
used at higher frequencies than its conventional leaded
counterparts.
