PE42440
Product Specification
Evaluation Kit
The SP4T switch EK Board was designed to ease
customer evaluation of Peregrine’s PE42440. The
RF common port is connected through a 50
transmission line via the top SMA connector, J1.
RF1, RF2, RF3 and RF4 are connected through
50 transmission lines via SMA connectors J3,
J5, J2 and J4, respectively. A through 50
transmission is available via SMA connectors J6
and J7. 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 four metal layer FR4
material with a total thickness of 62 mils.
The middle layers provide ground for the
transmission lines. The transmission lines were
designed using a coplanar waveguide with ground
plane model using a trace width of 32 mils, trace
gaps of 25 mils, and metal thickness of 2.1 mils.
