Description

M/A-COM’s MASW-007921 is a broadband GaAs

pHEMT MMIC SPDT switch available in a lead-free

2 mm 8-lead PDFN package. The MASW-007921 is

ideally suited for applications where very small size

and high linearity are required.

Typical applications include WiMAX, WLAN, Mesh

networks, fixed wireless access, and other higher

power systems. This switch has a very high initial

compression point, ideal for complex modulations

such as OFDM, with large peak average power

levels.

The MASW-007921 is fabricated using a 0.5 micron

gate length GaAs pHEMT process. The process

features full passivation for performance and

reliability.

3. M/A-COM recommends connecting unused pins to ground.

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

connected to RF and DC ground.

8. For positive voltage control, external DC blocking capacitors are required on all RF ports.

9. Performance can be optimized by varying the DC blocking capacitor value. See application schematic for details.

10. 0.05 - 2.0 GHz specifications apply with 1000 pF blocking capacitors. See applications section for typical data.

Handling Procedures

Please observe the following precautions to avoid

damage:

Static Sensitivity

Gallium Arsenide Integrated Circuits are sensitive

to electrostatic discharge (ESD) and can be

damaged by static electricity. Proper ESD control

techniques should be used when handling these

devices.

11. M/A-COM recommends connecting unused package pins

(N/C) to ground as shown.
