PE42430
Product Specification
Evaluation Kit Information
The SP3T Switch Evaluation Kit facilitates custom-
er evaluation of the PE42430 SP3T switch. The
RF common port is connected through a 50
Ω
transmission line to J2. Ports 1, 2 and 3 are con-
nected through 50
Ω
transmission lines to J3, J5
and J4 respectively. J1 provides digital inputs V1,
V2 and V3 to the device.
On the back of the board, a through line connects
SMA connectors J6 and J7. This transmission line
can be used to estimate the PCB loss over the
environmental conditions.
This four layer board is composed of Rogers 4350
on the top and bottom and FR4 on the inner layers
with a total thickness of 0.062”. All transmission
lines have 21.5 mil width and 7.25 mil gap.
Use jumpers on header J1 to short the control pins
to ground for logic low. V
DD
is supplied to the part
through at least one of the control pins via Pins 1,
3 or 5 (V3, V2, V1) on header J1.
