Title: Quadipole monolithic gaas pin diode switch
Inventor: SUCHIIBUN AARU NERUSON
IPC: H01L29/861
Filed: 1992-03-27
Abstract: PURPOSE: To obtain a monolithic GaAs PIN diode switch circuit which is possessed of wide-band characteristics and small in size, by a method wherein an outer circuit is connected to an input/output port and a bias node through a RF decoupling circuit. CONSTITUTION: When a bias A wire 22 and a bias B wire 24 are set at 1.5 to 5 volts and 0 volt or a negative voltage respectively, an arm between RF port A26 and C30 and another arm between RF port B28 and D32 are lessened in insertion loss. As a diode is biased ON, a direct current flows from the bias A wire 22 to the bias B wire 24, RF is blocked by a λ/4 choke 16 at a required operating frequency, a route from RF port A26 to D32 and another route from RF port 28 to C30 are biased OFF when the bias A wire 22 and the bias B wire 24 are kept at 1.5 to 5 volts and 0 volt respectively. Therefore, when two bias voltages are switched, the RF port D32 is switched to A26 or B28, and the RF port C30 is switched to B26 or a port 26 at the same time.
