FAQ

Q1: What does 2T2R mean?

2T2R stands for Two Transmit and Two Receive. This module integrates two PA transmit channels and two LNA receive channels, making it suitable for dual-channel wireless communication systems.

Q2: What is the maximum RF output power?

Each PA channel is specified for 10W output power, equivalent to approximately 40dBm. Actual output performance depends on the input drive level and operating conditions.

Q3: What frequency range does this module support?

The standard operating frequency range is 1440–1510MHz. Customized frequency ranges may be available upon engineering confirmation.

Q4: How is transmit/receive switching controlled?

The module uses TTL-level control signals. A high-level signal of 2–5V activates the PA and disables the LNA, while a low-level signal of 0V disables the PA and activates the LNA.

Q5: What power supply does the module require?

The specified supply voltage is +28V DC. The maximum current is listed as ≤1.7A per channel. Confirm the power supply requirements for your selected configuration before integration.

Q6: Can the RF connectors be customized?

Yes. MCX-KHD connectors are recommended for the RF ports, but the final connector configuration can be discussed according to your equipment design.

Q7: Is this module suitable for customized wireless communication equipment?

Yes. It is designed for integration into professional RF systems, and OEM/ODM customization is available for supported frequency ranges, connectors, and interface requirements.

Important Integration Notes
