Description
M/A-COM's MA4AGSW900-287T is a Gallium Arsenide SPST
PIN Diode Switch that makes use of Series Diodes featuring
Lower Loss, Higher Isolation and Faster Switching Speed. This
device is fabricated on OMCVD epitaxial wafers using a process
designed for high device uniformity and extremely low parasitics.
The switch die is fully passivated with silicon nitride and has an
additional layer of a polymer for scratch and impact protection.
This protective polymer coating provides additional moisture
protection to the SOT-23 assembly.
Applications
The small 20 fF capacitance, and the low 3.0 Ω
“ ON “ resistance of the GaAs PIN diodes allow for higher
isolation at zero volt bias and lower insertion loss vs.
comparable SPST switches. This switch is designed for use
in applications requiring improved RF performance, simple
D.C. Bias, and small device size.
