high isolation in a lead-free, plastic surface mount
package.
The MASWSS0178 is ideal for applications across a
broad range of frequencies including synthesizer
switching, transmit / receive switching, switch
matrices and filter banks in systems such as radio
and cellular equipment, PCS, GPS, and fiber optic
modules.
M/A-COM Technology fabricates the MASWSS0178
using a 1.0-micron gate length MESFET process.
The process features full chip passivation for
performance and reliability.

5. External DC blocking capacitors are required on all RF ports (47 pF capacitors are recommended). Use larger value capacitors for lower
frequency operation (e.g. use 10,000 pF capacitors to optimize insertion and return loss at frequencies below 50 MHz).
6. Terminated return loss is governed by blocking capacitors internal to the device; see applications plot.

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.
