Description
M/A-COM’s MASW-007587 is a broadband GaAs
PHEMT MMIC diversity switch available in a lead-
free 3 mm 12-lead PQFN package. The MASW-
007587 is ideally suited for applications where very
small size and high linear power are required.
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 MASW-007587 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.

5. Exceeding any one or combination of these limits may cause
permanent damage to this device.
6. M/A-COM does not recommend sustained operation near
these survivability limits.
7. Differential voltage, V (state 1) - V (state 0), must be
+2.7 V minimum and must not exceed 8.0 V.
8. 1 = +2.9 V to +8 V, 0 = 0 V + 0.2 V.
