PE4274
Preliminary Specification
Evaluation Kit
The SPDT Switch Evaluation Kit facilitates
customer evaluation of the PE4274 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 four metal layer FR4
material with a total thickness of 0.062”. The
transmission lines are hybrid microstrip/coplanar
waveguide with ground plane (28 mil core, 21 mil
width, 30 mil gap).
The provided jumpers short the control pins to
ground for logic low. With the jumper removed the
control input rises to V
1 MΩ pull up resistor. These resistors will draw
several microamps from V
required for normal operation.
