Description

The CXG1125ER is a high power antenna switch MMIC for PDC dual 800MHz and 1.5GHz. This IC is suited to connect 2Tx/3Rx to one of 4 antennas equipped with full packet mode. The CXG1125ER has on-chip logic circuit for operation with 6 CMOS inputs. The Sony's GaAs J-FET process is used for low insertion loss and low voltage operation.
