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.

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