PE95420 Datasheet, PDF (8/11 Pages) Peregrine Semiconductor Corp. – RF SPDT Switch Hermetically sealed ceramic package DC - 8500 MHz

Evaluation Board
The SPDT switch EK Board was designed to ease
customer evaluation of Peregrine’s PE95420. The RF
common port is connected through a 50 Ω transmission
line via the top SMA connector, J1. RF1 and RF2 are
connected through 50 Ω transmission lines via SMA
connectors J2 and J3, respectively. A through 50 Ω
transmission is available via SMA connectors J5 and
J6. 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
62 mils. The RF transmission lines were designed
using a Grounded co-planar waveguide with a linewidth
of 15 mils and gap of 7 mils.
