ADG904/ADG904-R
EVALUATION BOARD
The ADG904/ADG904-R evaluation board allows designers
to evaluate the high performance, wideband switches with
minimal effort.
Only a power supply and a network analyzer, along with the
evaluation board, are required to demonstrate that these devices
meet user requirements. An application note, available with the
evaluation board, provides complete operating information.
The RFC port (see Figure 30) is connected through a 50 Ω
transmission line to the bottom left SMA connector, J4. RF1,
RF2, RF3, and RF4 are connected through 50 Ω transmission
lines to SMA connectors J5, J6, J7, and J8, respectively. A through
transmission line connects J9 and J10; this transmission line
is used to estimate the loss of the PCB over the environmental
conditions being evaluated.
Figure 30. ADG904/ADG904-R Evaluation Board Top View
The board is constructed of four-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, clearance to ground plane of
0.008 inches, dielectric thickness of 0.02 inches, and a metal
thickness of 0.0021 inches.
