Typical applications include 2.5 & 3.5 GHz WiMax,
WLAN MESH networks, fixed wireless access, and
other higher power systems. Designed for high
power, this DPDT switch maintains high linearity up
to 4.0 GHz.
The MASWSS0184 is fabricated using a 0.5 micron
gate length GaAs PHEMT process. The process
features full passivation for performance and
reliability.

3. For positive voltage control, external DC blocking capacitors are required on all RF ports.
4. Insertion loss can be optimized by varying the DC blocking capacitor value. For use above 2.5 GHz, M/A-COM recommends using
smaller capacitor values. For example, use 5 pF for 3.2 GHz.
