Product Description
The RF1128 is a single-pole double-throw (SPDT) switch designed for gen-
eral purpose switching applications which require very low insertion loss
and high power handling capability. The RF1128 is ideally suited for bat-
tery operated applications requiring high performance switching with very
low DC power consumption. The RF1128 features very low insertion loss,
broadband isolation and excellent linearity performance, and is operable
from 1.8V to 3.3V control voltage. It is fabricated with 0.5m GaAs
pHEMT process, and is packaged in a very compact 2mmx1.3mm, 6-pin,
leadless QFN package.
