Description

The M/A-COM MASWSS0178 GaAs monolithic

switch provides high isolation in a lead-free, plastic

surface mount package.

Pin Configuration ²

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.

2. The exposed pad centered on the package bottom must be

connected to RF and DC ground.

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.
