EVAL-ADG936EB/EVAL-ADG936REB
The EVAL-ADG936EB/EVAL-ADG936REB allow designers to
evaluate the high performance wideband switches with a
minimum of effort.
The RFCA port is connected through a 50 Ω transmission line
to a SMA connector, J3, and the RFCB port is connected
through a 50 Ω transmission line to a SMA connector, J4.
RF1A, RF2A, RF1B, and RF2B are connected through 50 Ω
transmission lines to the SMA Connectors J5, J6, J7, and J8,
respectively. A through transmission line connects J9 and J10,
which is used to estimate the loss of the PCB over the
environmental conditions being evaluated (see
Figure 2).
The board is constructed of a 4-layer FR4 material with a dielectric
constant of 4.3 and an overall thickness of 0.062 inches. Two
ground layers with grounded planes provide ground for the RF
transmission lines. The transmission lines were designed using
a coplanar waveguide with a ground plane model using a trace
width of 0.024 inches, a clearance to ground plane of 0.008 inches,
a dielectric thickness of 0.02 inches, and a metal thickness of
0.0021 inches.
Two 10 μF surface-mount tantulum decoupling capacitors are
provided on the V
DD
line, with one placed close to the DUT
along with a 100 pF ceramic capacitor on the V
DD
line.
