Evaluation Kit

The SPDT Switch Evaluation Kit board was

designed to ease customer evaluation of the

PE4235 SPDT switch. The RF common port is

connected through a 50 Ω transmission line to the

top left SMA connector, J1. Port 1 and Port 2 are

connected through 50 Ω transmission lines to the top

two SMA connectors on the right side of the board,

J2 and J3. A through transmission line connects

SMA connectors J4 and J5. 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 two metal layer FR4

material with a total thickness of 0.031”. The bottom

layer provides ground for the RF transmission lines.

The transmission lines were designed using a

coplanar waveguide with ground plane model using

a trace width of 0.0476”, trace gaps of 0.030”,

dielectric thickness of 0.028”, metal thickness of

0.0021” and ε_rof 4.4.

J6 provides a means for controlling DC and digital

inputs to the device. Starting from the lower left pin,

the second pin to the right (J6-3) is connected to the

device CTRL input. The fourth pin to the right (J6-7)

is connected to the device V_DDinput. A decoupling

capacitor (100 pF) is provided on both CTRL and

V_DDtraces. It is the responsibility of the customer to

determine proper supply decoupling for their design

application. Removing these components from the

evaluation board has not been shown to degrade RF

performance.
