U1 SKY13278-313
Printed Circuit Board Skyworks SK39990
Evaluation Board
The evaluation board for the SKY13278-313 allows the switch to
be fully exercised. The RF common port is marked “J
1
”, and the
two switched RF ports are marked “J
2
and “J
3
”. All of the RF
ports have SMA connectors mounted. The control voltage inputs
are marked “V
1
and “V
2
”.
The printed circuit board material is FR4. The RF dielectric layer
is 0.012 inches thick, ½ oz. copper. The RF transmission lines are
each 50 (nominal) microstrip.
There are three DC blocking capacitors on the board, C
1
, C
2
and
C
3
, each of which is in series with one of the RF ports. These
capacitors are 47 pF. For improved insertion loss at signal fre-
quencies below approximately 500 MHz these capacitors should
be replaced with larger capacitance capacitors, such as 1000 pF.
