SP5T Absorptive UltraCMOS® High-Isolation RF Switch 450-4000 MHz, VssEXT option

Peregrine Semiconductor Corp. 

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 Ω transmission

line via the top SMA connector. RF1, RF2, RF3 and

RF4 are connected through 50 Ω transmission lines via

side SMA connectors. A through 50 Ω transmission is

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 VssEXT are heavily

isolated from one another, otherwise the true

performance of the PE42451 will not be yielded.
