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 W
“ 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.

Mounting Information
MA4AGSW900-287T
V 1.00
The illustration indicates the recommended mounting pad configuration for the SOT-23package. Solder paste containing flux
should be screened onto the pads to a thickness of 0.005- 0.007 inches. The plastic package device is placed in position,
firmly adhering to the solder past.
Permanent attachment is performed by a reflow soldering procedure during which the tab temperature does not exceed
+275 °C and the body temperature does not exceed +250 °C.

Static Sensitivity
MA4AGSW900-287T
V 1.00
Gallium Arsenide PIN diodes are ESD sensitive and can be damaged by static electricity. Proper ESD techniques should be
used when handling these devices.
Operation of the MA4AGSW900-287T SPST Switch
Successful operation of the SPST Switch is accomplished by connecting J1 ( PIN 1 ) to a RF Bias Network , J2 ( PIN 2 ) to a
DC Return Network , and SOT-23 Ground ( PIN 3 ) to Circuit RF and D.C. Ground. Approximately + 3.0 V @ + 5 mA will
create the Insertion Loss State, and 0 V will produce the Isolation State. The Isolation value is improved slightly by applying
–3 V D.C. Bias. The SPST switch can be driven from a simple + 5 V TTL Gate Driver.
