Shenzhen Mingjiada Electronics Co., Ltd. supplies and recycles the Qorvo AWS-0101, a highly integrated silicon-based quad-core X-band beamformer operating from 8.5 GHz to 10.55 GHz.
The AWS-0101 is a silicon-based quad-core beamformer integrated circuit (BFIC) designed for X-band phased array systems, operating in the 8.5 GHz to 10.55 GHz frequency range. It integrates four RF channels and supports single-beam transmission and dual-beam reception architectures, significantly simplifying the hardware design of active electronically scanned array (AESA) antennas whilst effectively reducing system size, weight, power consumption and cost (SWaP-C). It serves as the core RF chip for commercial radar, weather radar and X-band communication arrays.
I. Core Overview of the AWS-0101 Product
The AWS-0101 utilises a silicon-based process to achieve high integration, with a single chip supporting four radiating element RF links and incorporating complete adjustable gain units, phase shifters and signal combiner networks. The chip integrates all RF functions required for beam control, eliminating the need for a large number of external discrete phase shifters and attenuators; when paired with an external T/R switch, it forms a plug-and-play array channel solution.
The device is powered by a single supply and features a standardised SPI digital control interface. It supports multi-chip cascading for networking, facilitating large-scale array expansion and making it suitable for the development of active phased array antennas ranging from small 4-element modules to those comprising hundreds of elements.

III. Core Technical Advantages of the AWS-0101
Highly integrated silicon-based solution, streamlining the BOM
Integrates four channels of attenuation, phase shifting and signal synthesis circuits onto a single chip, replacing traditional discrete RF component solutions. This reduces the number of components, shortens the debugging cycle and is suitable for mass production.
Unique dual-receive-beam architecture
Two independent receive beams are formed simultaneously within the same array aperture, enabling simultaneous multi-target detection, interferometric angle measurement and interference suppression. Compared to single-beam receive chips, this offers superior radar signal processing capabilities.
High-speed electronically controlled beam scanning
6-bit digital phase shifting and gain adjustment, supporting real-time software updates to beam weights, enabling high-speed electronic beam steering. The absence of mechanical scanning mechanisms ensures higher reliability.
Excellent Array Scalability
An SPI daisy-chain architecture allows multiple AWS-0101 chips to be controlled centrally, facilitating the easy construction of 16/32/64-element, or even larger-scale, planar phased arrays.
Suitable for Both Military and Commercial Applications
The silicon-based process balances RF performance with cost, meeting the requirements of low-power AESA radars whilst also being suitable for commercial, high-volume meteorological radars and security detection radars.
IV. Typical Application Scenarios for the AWS-0101
Commercial weather radars, small-scale low-altitude detection radars
Ground-based and airborne lightweight X-band active phased array radars (AESA)
X-band point-to-point directional communication phased array antennas
R&D platforms for 5G and next-generation wireless communication RF active arrays
Electronic warfare receiver arrays, small-scale RF sensing systems
V. Summary of the AWS-0101
The AWS-0101 is a highly competitive silicon-based quad-core beamformer in the X-band phased array sector. Leveraging the 8.5–10.55 GHz standard frequency band, a 4-channel integrated architecture, dual-receiver/single-transmitter beam capabilities and 6-bit high-precision amplitude and phase control, it plays a vital role in active array systems designed for miniaturisation, low power consumption and low cost. Whether for the large-scale deployment of commercial radar systems or the development of lightweight defence RF phased arrays, the AWS-0101 is a mature and reliable choice for core RF components.
