Description
M/A-COM’s SW-277 is a GaAs MMIC SPDT switch
in a SOIC-8 lead surface mount plastic package.
The SW-277 is ideally suited for use where low
power consumption is required.
Typical
applications
include transmit/receive
switching, switch matrices and switched filter banks
in systems such as radio and cellular equipment,
PCM, GPS, fiber optic modules, and other battery
powered radio equipment.
The SW-277 is fabricated using a monolithic GaAs
MMIC using a mature 1 micron process. The
process features full chip passivation for increased
performance and reliability.

All specifications apply when operated with control voltages of 0 V for VC low and 5 to 10 V for VC high, and 50 Ω impedance at all RF
ports, unless otherwise specified. High power (greater than 1 W) handling specifications apply to cold switching only. For input powers
under 1 W, hot switching can be used. The high control voltage must be within ± 0.2 V of the supply voltage. External DC blocking
capacitors are required on all RF ports.
Typical values listed for middle of frequency range noted.

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.
