Description
The M/A-COM MASWSS0178 GaAs monolithic
switch provides 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 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.
