Description
M/A-COM’s MASW-008075 is a GaAs PHEMT
MMIC SPDT switch in a lead-free SC-70 (SOT-363)
surface mount plastic package. The MASW-008075
is ideally suited for applications where very small
size and low cost are required.

RF2
Typical applications are transmit / receive (Tx / Rx)
switching in linear systems such as WLAN 802.11b/
g. Other applications include 1.9 GHz and 2.4 GHz
DECT and linear systems operating up to 3.0 GHz.
The MASW-008075 is fabricated using a 0.5 micron
gate length GaAs PHEMT process. The process
features full passivation for performance and
reliability.

4. For positive voltage control, external DC blocking capacitors are required on all RF ports.
5. Insertion Loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 100 MHz – 1.0 GHz, 39 pF for 0.5 - 3.0 GHz.

Handling Procedures
The following precautions should be observed to
avoid damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be dam-
aged by static electricity. Proper ESD control tech-
niques should be used when handling these de-
vices.
†
Reference Application Note M538 for lead-free solder reflow
recommendations.
Meets JEDEC moisture sensitivity level 1 requirements.
