ADG936/ADG936-R
EVALUATION BOARD
The ADG936 and ADG936-R evaluation board allows
designers to evaluate these high performance wideband
switches with minimal effort.
To prove that these devices meet the user’s requirements, only a
power supply and a network analyzer, along with the evaluation
board, are required. An application note available with the
evaluation board gives complete information on operating the
evaluation board.
The RFCA port is connected through a 50 Ω transmission line
to SMA connector J3. The RFCB port is connected through a
50 Ω transmission line to SMA connector J4. RF1A, RF2A,
RF1B, and RF2B 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.
The board is constructed of a four-layer, FR4 material with a
dielectric constant of 4.3 and an overall thickness of 0.062 in.
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 0.024 in, clearance to ground plane of 0.008 in,
dielectric thickness of 0.02 in, and a metal thickness of
0.0021 in.
