FDD RF Power Amplifier – Custom Frequency TX/RX Amplifier

Overview

The FDD RF Power Amplifier is a professional radio frequency amplification solution designed for Frequency Division Duplex (FDD) wireless communication systems. It supports simultaneous transmission and reception on separate frequency bands, combining a high-power transmit path with a low-noise receive path.

Designed for professional wireless equipment manufacturers and system integrators, this amplifier offers customizable frequency bands, output power levels, RF interfaces, and mechanical configurations. It is suitable for COFDM video transmission, UAV communication links, ground stations, and other applications requiring reliable RF signal amplification.

Key Features

FAQ

Q1: Can the FDD RF amplifier support custom frequencies?

Yes. The frequency plan can be customized according to your application. Very wide frequency coverage may require segmented designs to maintain performance.

Q2: Can the amplifier transmit and receive simultaneously?

Yes. It is designed for FDD operation, where transmission and reception use separate frequency bands. Proper filtering and TX/RX isolation must be matched to your system.

Q3: What output power options are available?

Typical configurations include 1 W, 2 W, 5 W, and 10 W. Additional single-channel 20 W and 50 W configurations are also listed as custom options. Availability depends on the frequency band and design.

Q4: Is it suitable for COFDM video transmission?

Yes. It is designed for RF systems using COFDM and other supported digital modulation schemes, subject to the selected configuration and system requirements.

Q5: Can the RF interface and enclosure be customized?

Yes. SMA, MMCX, and custom RF interfaces are available options. Board-level and enclosed versions can be discussed for OEM integration.

Q6: What information should I provide when requesting a quotation?

Please provide your TX frequency, RX frequency, required output power, modulation type, DC supply requirements, RF connector preference, and preferred mechanical configuration.
