Evaluation Kit
The SPDT switch EK Board was designed to ease
customer evaluation of Peregrine’s PE42552. The
RF common port is connected through a 50 Ω
transmission line via the top SMA connector, J1.
RF1, RF2, RF3 and RF4 are connected through
50 Ω transmission lines via SMA connectors J3,
J5, J2 and J4, respectively. A through 50 Ω
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 evaluation kit board is constructed of four
metal layers. The dual clad top RF layer is
Rogers RO4003 material with an 8 mil RF core
and er = 3.55. The other two dielectric layers are
FR4 for DC control and overall board strength with
an cumulative board thickness of 60 mils. The RF
transmission lines were designed using a
Grounded co-planar waveguide with a linewidth of
15 mils and gap of 10 mils.
