GaAs IC Transfer Switch DC–2 GHz
Features
■ High Linearity (+45 dBm IP3 @ 0.9 GHz)
■ Small MSOP-8 Plastic Package
■ Low Insertion Loss (0.4 dB @ 0.9 GHz)
■ Simultaneous T/R Switching
Description
The AS127-59 is a 4 port switch designed to combine T/R
and antenna changeover switching capability within one
device. This switch has two 5 V controls and is ideal for
applications requiring low power consumption. The
AS127-59 has excellent performance to 2 GHz making it
suitable for dual-band handset designs.
