AV transmitter Yealink PA20 Black 3840 x 2160 pixels Wired Wireless

PA20 is a wireless presentation adapter that provides up to 4K/30fps resolution and low-latency performance. Equipped with a 2x2 MIMO Wi‑Fi 6 module, it supports dual-band 2.4GHz/5GHz connections and is designed to deliver smooth, responsive screen sharing with improved anti-interference capability.

Advantages

The PA20 offers high-definition 4K presentation with reduced latency for real-time interaction. Its 2x2 MIMO Wi‑Fi 6 ensures stable wireless transmission and better resistance to interference. The adapter uses a hardware encoding chip and supports USB Type‑C devices for a plug-and-play experience without installing drivers or occupying the host CPU.

Key specifications

• Maximum output: 4K at 30 fps
• Wireless: Wi‑Fi 6, 2x2 MIMO
• Frequency bands: 2.4 GHz and 5 GHz (dual-band)
• Latency: low-latency operation (real-time presenting)
• Interface: USB Type-C compatible devices
• Driver: no extra driver required (hardware encoding)

How to use

Connect the PA20 to a compatible display or host device using the USB Type‑C interface and select the adapter as the output or casting source on your device. Ensure the host device supports full-featured USB Type‑C and wireless display or screen sharing. Once connected, the built-in hardware encoder handles video transmission without additional software or driver installation.

Recommendations

For best performance, use a dual-band Wi‑Fi network with a clear 5 GHz channel and position the PA20 and the host device within good signal range. Verify that your device supports full-featured USB Type‑C and that no power‑only adapters are used.
