Evaluation Kit
The SP5T switch EK Board was designed to ease
customer evaluation of Peregrine’s PE42451. The RF
common port is connected through a 50
line via the top SMA connector. RF1, RF2, RF3 and
RF4 are connected through 50
side SMA connectors. A through 50
available via SMA connectors RFCAL1 and RFCAL2.
This transmission line can be used to estimate the loss
of the PCB over the environmental conditions being
evaluated.
The EVK board is constructed with four metal layers on
dielectric materials of Rogers 4003C and 4450 with a
total thickness of 32 mils. Layer 1 and layer 3 provide
ground for the 50 ohm transmission lines. The 50 ohm
transmission lines are designed in layer 2 for high
isolation purpose and use a stripline waveguide design
with a trace width of 9.4 mils and trace metal thickness
of 1.8 mils. The board stack up for 50 ohm transmission
lines has 8 mil thickness of Rogers 4003C between
layer 1 and layer 2, and 10 mil thickness of Rogers
4450 between layer 2 and layer 3. Please consult
manufacturer's guidelines for proper board material
properties in your application. The PCB should be
designed in such a way that RF transmission lines and
sensitive DC i/o traces such as Vss
isolated from one another, otherwise the true
performance of the PE42451 will not be yielded.
