The SPDT Switch Evaluation Kit facilitates

customer evaluation of the PE42750 SPDT switch.

The RF common port is connected through a 75 Ω

transmission line to J2. Ports 1 and 2 are

connected through 75 Ω transmission lines to J1

and J3. A through line connects F connectors J4

and J5. This transmission line can be used to

estimate the PCB loss over the environmental

conditions. J6 provides DC and digital inputs to the

device.

The board is composed of a two metal layer FR4

material with a total thickness of 0.032”. The

transmission lines are hybrid microstrip/coplanar

waveguide with ground plane (28 mil core, 12 mil

width, 12 mil gap).

The provided jumpers short the control pins to

ground for logic low. With the jumper removed the

1 MΩ pull up resistor. These resistors will draw

for normal operation.
