Description
The SKY19225-001 is a wafer level chip scale package (WLCSP)
single-pole, four-throw (SP4T) switch designed for antenna tuning
applications that require very low RON and COFF. The
SKY19225-001 can also be used for LTE/WCDMA/GSM transmit
applications. Switching is controlled by an integrated GPIO
interface with two control pins and an Enable pin. Depending on
the logic voltage level applied to the control pins, the antenna port
is connected to one of the four switched RF outputs through a low
insertion loss path, while the path between the antenna port and
the other RF ports is in a high-isolation state.
No external DC blocking capacitors are required as long as no DC
voltage is applied on any RF path.
The SKY19225-001 is provided in a compact 11-bump,
1.685  1.685  0.547 mm WLCSP that meets requirements for
board-level assembly. Bump diameters are 262 microns with a
minimum bump pitch of 400 microns.
A functional block diagram is shown in Figure 1.
