ADG9xx EVALUATION BOARD
The ADG9xx evaluation board allows designers to evaluate the
high performance wideband switches with a minimum of effort.
In addition to the evaluation board, the user requires only a
power supply and a network analyzer. An application note is
available with the evaluation board and gives complete
information about operating the evaluation board.
The RFC port (see Figure 29) is connected through a 50 Ω
transmission line to the top left SMA connector J1. RF1 and
RF2 are connected through 50 Ω transmission lines to the top
two SMA connectors, J2 and J3 respectively. A through trans-
mission line connects J4 and J5 and 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 transmission lines
were designed using a coplanar waveguide with ground plane
model using a trace width of 0.052 inches, a clearance to ground
plane of 0.030 inches, a dielectric thickness of 0.029 inches, and
a metal thickness of 0.014 inches.
