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.

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.

1. Reference Application Note M513 for reel size information.

2. All sample boards include 5 loose parts.

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.
