V 1.00
Static Sensitivity
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.
