GaAs IC SPDT Reflective Switch
Positive Control DC–2.5 GHz
Features
■ Low Insertion Loss (0.4 dB @ 0.9 GHz)
■ Complementary Positive Control Voltages
(0/+3 V to 0/+5 V)
■ Positive Voltage Supply (+3 to +5 V)
■ Low DC Power Consumption
■ Ultra Miniature 6 Lead SOT-6 Package
Description
The AS125-73 is a GaAs IC FET SPDT reflective switch
in the SOT-6 plastic package for commercial applications.
For positive operation it requires a fixed positive bias (V_S)
on the J₁ line and DC blocks on all RF lines. This switch
can also be operated with complementary negative
voltage (no V_S or blocking caps required). The AS125-73
provides a low cost solution for IF switching requirements
in dual-band and dual mode subscribers.
