High-quality RF IPD baluns
for ISM bands
VISUAL ZONE
Simplify RF complexity
The tremendous growth of
Internet of Things is leading to
the development of increasingly
smaller wearables that require
easy-to-implement electronic
components in environments
with higher densities.
Tuned for high RF integration, ST’s
RF IPD baluns provide improved
system performances while
simplifying RFIC to antenna
matching network complexity.
KEY BENEFITS
KEY APPLICATIONS
Integration
• Beacons
• Integrated matched balun with harmonic
• Wireless toys
filter
• Less than 560 µm height after reflow
• Smart watches
• Smartbands
Performance
• Drones
• Improve RF performance
• Low insertion loss
• Thermostats
• Fitness devices
• Low amplitude imbalance
• Low phase imbalance
Simplicity
In addition, designed with
integrated harmonic filters, they
make it easy to comply with
major EMC regulations.
• Replaces twisty discrete SMD matching
network
• Single-chip solution
