DATA SHEET
SKY13296-340LF: GaAs SP4T Absorptive Switch
20 MHz–2.5 GHz
Features
G Positive voltage control (0/3 V to 0/5 V)
G High isolation 35 dB at 1 GHz
G Integrated silicon CMOS driver
G Isolated ports are absorptive
G Use of external DC blocks to allow good return loss
to low frequency
G Available lead (Pb)-free and RoHS-compliant MSL-1 @ 260 °C
per JEDEC J-STD-020
Description
The SKY13296-340LF is a pHEMT GaAs FET IC high isolation,
absorptive single-pole four-throw switch packaged in a lead
(Pb)-free, 4 x 4 mm, 20-lead exposed-pad plastic package for
low-cost commercial applications. The use of external DC
blocking capacitors on the RF ports and in series with the
internal RF terminations enables the user to extend the range
of good return loss to arbitrarily low frequency. This switch
is an ideal building block for filter bank switching.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
