Description
The ZL70323 implantable radio module implements all RFrelated functions needed to deploy the implantable node in a
MICS-band RF telemetry system. The integrated antenna
tuning circuit allows the module to be used with a wide range of
implantable antennas (nominal antenna impedance is
100+j150Ω). Figure 1 shows the module’s major subsystems:
• ZL70103-based MICS-band RF transceiver with an
integrated matching network, SAW filters for suppression of
unwanted blockers, and antenna tuning.
• 2.45-GHz wake-up receiver matching network.
• Integrated 24-MHz reference frequency crystal.
• Decoupling capacitors.

Applications
• Implantable Medical Devices
– Cardiac Rhythm Management
– Neurostimulators
– Drug Delivery, Sensors, and Diagnostics
