company blog about Qorvo AWMF-0147 High Integrated Tx Beamformer For Satellite Communications Applications

Shenzhen Mingjiada Electronics Co., Ltd. supplies and recycles the Qorvo AWMF-0147 highly integrated transmit beamformer, suitable for satellite communications applications.

I. AWMF-0147 Product Overview

The AWMF-0147 is a Ku-band 4×2 quad-core transmit beamformer integrated circuit launched by Qorvo (formerly Anokiwave). It forms part of the second-generation satellite communications beamformer product series and has been specifically developed for phased-array flat-panel antennas on LEO/MEO/GEO satellites. As a highly integrated silicon-based SoC, this device fully integrates multi-channel RF control circuits and supports four sets of dual-polarisation radiating elements on a single chip, significantly simplifying the active phased array transmit front-end architecture. It effectively reduces the size, power consumption and bill of materials of the antenna system, making it the core RF chip for phased array antennas in in-flight satellite terminals and fixed satellite ground stations.

The AWMF-0147 operates in the 13.75–14.5 GHz Ku-band uplink frequency range, making it compatible with mainstream satellite communication transmission links. When paired with the AWMF-0146 receive beamformer from the same series, it enables the construction of a complete Ku-band integrated transmit-receive phased array solution, widely empowering lightweight flat-panel satellite communication terminals.

II. Core Functions and Key Features of the AWMF-0147

1. RF Channel Architecture

A Ku-band 4×2 transmit beamformer, with a single chip driving four dual-polarisation radiating elements, supporting independent control of two polarisation channels; compatible with right-hand circular polarisation (RHCP), left-hand circular polarisation (LHCP) and linear polarisation operating modes, offering flexible polarisation configuration to suit the polarisation standards of different satellite systems.

2. High-Precision Beam Control Capabilities

6-bit phase control enables fine-tuned beam pointing adjustment, ensuring high-speed beam switching capability to meet the rapid transit tracking requirements of low-Earth orbit satellites;

5-bit gain control supports channel amplitude equalisation, suppresses array sidelobes and optimises the far-field radiation pattern;

Built-in temperature-adaptive gain compensation circuitry ensures stable channel gain consistency across a wide temperature range, reducing the burden of system-wide calibration.

3. Integrated Monitoring and Protection Design

Equipped with on-chip temperature detection and telemetry reporting functions, the main control system obtains the chip’s operating temperature in real time, facilitating the scheduling of system thermal management strategies; all pins feature built-in ESD protection, enhancing the device’s reliability in complex operating environments such as outdoor and vehicle-mounted applications.

4. Low Power Consumption and Miniaturised Packaging

Utilises a single +1.2V power supply, significantly reducing the array’s overall power consumption; the WLCSP (Wafer-Level Chip-Scale Packaging) offers a compact form factor, facilitating direct mounting onto the radiating element substrate to achieve tile-based integration of the RF front-end, making it highly suitable for ultra-thin flat phased array layouts and simplifying thermal design.

III. Technical Advantages of the AWMF-0147

High Integration: Highly integrated design incorporating phase shifters, variable gain amplifiers, polarisation switching and digital control interfaces, reducing the number of external passive components, shortening RF traces on the PCB and minimising RF losses;

Suitable for ‘Communication on the Move’ Scenarios: Supports rapid beam scanning, automatic satellite acquisition and continuous tracking, meeting the ‘Communication on the Move’ requirements for vehicle-, ship- and aircraft-based satellite communications;

Easy array expansion: Cascading multiple AWMF-0147 modules enables the construction of large-scale phased array antennas, whilst the modular design shortens the antenna development cycle;

Commercially viable: Silicon-based processes offer cost advantages, significantly reducing the mass production costs of large-scale arrays compared to traditional discrete MMIC solutions.
