Sony CXG1134EN Datasheet

CXG1134EN

High P ower SPDT Switch with Logic Control

Description

The CXG1134EN is a high power and high Isolation
SPDT switch MMIC. This IC can be used in wireless
communication systems. The CXG1134EN can be
operated by one CMOS control line. The Sony GaAs
J-FET process is used f or low insertion loss and on-chip
logic circuit.
