Description

M/A-COM‘s MASW-008955 is a GaAs pHEMT

MMIC single pole three throw (SP3T) switch in a

lead-free 2 mm 8-lead PDFN package. The MASW-

008955 is ideally suited for applications where low

control voltage, low insertion loss, high isolation,

small size, and low cost are required.

Typical applications are for filter and antenna

switching in WLAN or Bluetooth systems that

connect separate receive functions to a common

antenna This part can be used in all systems

operating up to 3.5 GHz requiring low control

voltage.

The MASW-008955 is fabricated using a 0.5 micron

gate length GaAs pHEMT process. The process

features full passivation for performance and

reliability.

3. Depending on system sensitivity optional DC line bypass

capacitors (22 pF) may be used.

4. Improved linearity at low control voltage can be obtained by

tying pin 2 to the most positive control voltage. Otherwise,

leave pin 2 unconnected.

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

8. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 100 pF for 100 - 500 MHz, 39 pF for 2.45 GHz.

9. Specifications apply with no connection to pin 2 (VP).

10. 0 = 0 V ± 0.2 V, 1 = 1.8 V to +5 V, minimum VHI-VLO = 1.8 V,

maximum VHI-VLO = 8.5 V.

11. For use at low voltage, M/A-COM recommends connecting

pin 2 to a voltage equal to the most positive control voltage.

12. Negative control voltage may be used. The ‗1‘ in the table

would be the most positive (0 V) and the ‗0‘ would be the

most negative (-3 V for example).

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.
