Description
The CSW0118-BD is a single-pole double-throw
(SPDT) GaAs pHEMTMMIC switch that covers the frequen-
cy range from 0.5 to 18 GHz. The CSW0118-BD is 80%
smaller than comparable broadband FETswitch MMICs offer-
ing similar performance. It has very low power consumption
requirements and offers very fast switching speeds.
The 0.5 µm pHEMT GaAs process used for this device provides
for excellent uniformity and high manufacturing yields.
Backside via holes are used to provide low induc-
tance ground connections and to facilitate ease of use. Gold-
plated metallization in used on both front side and backside
metal. The MMIC is compatible with either eutectic or con-
ductive epoxy die attach and either thermocompression or
thermosonic wire bonding.Minimal off-chip components pro-
vides ease of use in design and manufacturing steps.
CSW0118-BD SPDTMMIC switches are shipped in
Gel Pack.
