Evaluation Kit
The SPST Switch Evaluation Kit board was
designed to ease customer evaluation of the
PE4246 SPST switch. The RF1 port is connected
through a 50
transmission line to the top left
SMA connector, J1. The RF2 port is connected
through a 50
transmission line to the top right
SMA connector, J2. A through transmission line
connects SMA connectors J3 and J4. This
transmission line can be used to estimate the loss
of the PCB over the environmental conditions
being evaluated.
The board is constructed of a two metal layer FR4
material with a total thickness of 0.031”. The
bottom layer provides ground for the RF
transmission lines. The transmission lines were
designed using a coplanar waveguide model with
trace width of 0.0476”, trace gaps of 0.030”,
dielectric thickness of 0.028”, metal thickness of
0.0021” and
εR of 4.3. Note that the predominate
mode for these transmission lines is coplanar
waveguide with a ground plane.
J5 and J6 provide a means for controlling DC and
digital inputs to the device. J6-1 is connected to
the device VDD input. J5-1 is connected to the
device CTRL input. J5-2 and J6-2 are GND
connections. A decoupling capacitor (100 pF) is
provided on both CTRL and VDD traces. It is the
responsibility of the customer to determine proper
supply decoupling for their design application.
Removing these components from the evaluation
board has not been shown to degrade RF
performance.
