switch in a low cost lead-free SOT-26 surface mount
plastic package. The MASW-007935 is ideally suited
for applications where very low power consumption,
low insertion loss and very small size are required.
Typical application is in dual band systems which
require switching between small signal components
such as filter banks, single band LNA's, converters
etc. The MASW-007935 can be used in applications
up to 0.25 Watts in systems such as CDMA, W-
CDMA, PCS, DCS1800, GSM and other analog/
digital wireless communications systems.
The MASW-007935 is fabricated using a mature 0.5
micron GaAs PHEMT process. The process features
full passivation for increased performance and
reliability.

2. External DC blocking capacitors are required on all RF ports when using positive voltage control.
3. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 100 MHz - 1 GHz, 39 pF for 0.5 GHz - 3 GHz.

4. Exceeding any one or combination of these limits may cause
permanent damage to this device.
5. M/A-COM does not recommend sustained operation near
these survivability limits.
6. External DC blocking capacitors are required on all RF ports
and GND. GND capacitors can be used with positive control
voltage to resonate lead inductance for improved isolation.
7. If negative control is used, DC blocking capacitors and GND
capacitors are not required.
