Description

The MASWSS0157 is a GaAs MMIC SPDT switch in

a lead-free SOIC 8-lead surface mount plastic

package. This device is ideally suited for use where

low power consumption is required.

Typical applications include transmit/receive

switching, switch matrices and switched filter banks

in systems such as radio and cellular equipment,

PCM, GPS, fiber optic modules, and other battery

powered radio equipment.

The MASWSS0157 is fabricated using a monolithic

GaAs MMIC using a mature 1 micron process. The

process features full chip passivation for increased

performance and reliability.

2. For positive voltage control, external DC blocking capacitors are required on all RF ports as well as the Ground ports which should be

pulled up to the positive voltage control level. (Refer to Application Note M521 - "Positive Voltage Control of GaAs MMIC Control Devices").

Handling Procedures

Please observe the following precautions to avoid

damage:

Static Sensitivity

Gallium Arsenide Integrated Circuits are sensitive

to electrostatic discharge (ESD) and can be

damaged by static electricity. Proper ESD control

techniques should be used when handling these

devices.
