01 AI-Thinker Ai-SG Series

Not just a “wireless module”, but an ultimate RF front-end module

The Ai-SG01 / Ai-SG01-P are based on Panqi Micro’s next-generation PAN3120 RF chip, designed for industrial and IoT scenarios with extremely high requirements for size, performance, and stability.

• Frequency bands: 420–445 MHz, 470–510 MHz (optional)
• Receiver sensitivity: –121 dBm
• Transmit power: +20 dBm
• Size: 12 × 13 × 2.4 mm
• SMD-16 / castellated (stamp-hole) interface

Its core advantage lies in extreme miniaturization combined with top-tier RF performance.

03 Ai-SG01-P

Industrial-grade module built for range + power

Solves thermal accumulation risks during long-term high-power operation

One of the key highlights of Ai-SG01-P:

• PAE up to 41>#/span###
• Continuous transmission at 30 dBm
• Module surface temperature only 32–45 °C
• Antenna impedance mismatch protection
• Stable operation under no-load and abnormal conditions

Completely solves the long-standing “antenna burns the module” problem

Designed specifically for real industrial environments:

• Antenna impedance mismatch protection
• Stable operation under no-load and abnormal conditions

Even when:

• Antenna is not connected
• Antenna is mismatched
• Misoperation occurs on site
• The module continues to operate reliably.
