ADG90x EVALUATION BOARD
The ADG90x evaluation board allows designers to evaluate the
high performance wideband switches with a minimum of effort.
To prove that these devices meet user requirements, the user
requires only a power supply and a network analyzer along with
the evaluation board. An application note is available with the
evaluation board and provides complete information on
operating the evaluation board.
The RF1 port (see Figure 23) is connected through a
50 Ω transmission line to the top left SMA Connector J1. RF2 is
connected through a 50 Ω transmission line to the top SMA
Connector J2. J3 is connected to GND. A through transmission
line connects J4 and J5 and this transmission line is used to
estimate the loss of the PCB over the environmental conditions
being evaluated.
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 trans-

mission lines were designed using a coplanar waveguide
with ground plane model using a trace width of 0.052 inches,
clearance to ground plane of 0.030 inches, dielectric thickness
of 0.029 inches, and a metal thickness of 0.014 inches.
