Product Specification
Evaluation Kit
The SPDT Switch Evaluation Kit board was designed to
Figure 8. Evaluation Board Layouts
Peregrine Specification 101/0151
ease customer evaluation of the PE4257 SPDT switch.
The RF common port is connected through a 50 ?
transmission line to J2. Port 1 and Port 2 are
connected through 50 ? transmission lines to J1 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 four metal layer FR4
material with a total thickness of 0.031”. The
transmission lines were designed using a coplanar
waveguide with ground plane (28 mil core, 47.6 mil
width, 30mil gap).
Note the number of vias surrounding the device in the
layout shown in Figure 8. These vias are critical for
obtaining the specified isolation performance for the
device shown in this datasheet.
J6 provides a means for controlling DC and digital
inputs to the device. The provided jumpers short the
package pin to ground for logic low. When the jumper
is removed, the pin is pulled up to VDD for logic high.
When the jumper is in place, 3 μA of current will flow
through the 1 M ? pull up resistor. This extra current
should not be attributed to the requirements of the
device.
