In-Depth Internal Component Analysis
Multi-Board Assembly with Integrated Antenna Array
A detailed inspection of the device’s internals reveals a highly modular architecture comprising several densely populated PCBs, a sophisticated antenna array, and substantial mechanical shielding. The most striking feature is the large, gold-plated planar patch antenna array, likely engineered for operation in the 24 GHz ISM band. This array, situated at the top left, consists of a regular grid of square patches—an arrangement optimized for omnidirectional coverage and beamforming capabilities. The top right PCB hosts a major system-on-chip or FPGA (in a large BGA package), flanked by memory and support ICs, forming the digital signal processing heart of the radar. The lower left PCB is populated with numerous smaller ICs, including likely candidates for RF front-end roles (mixers, LNAs, power amplifiers) and analog-to-digital converters, all interconnected by high-speed board-to-board connectors. The PCBs exhibit meticulous RF layout, with controlled-impedance traces, extensive ground pours, and stitching vias, ensuring signal integrity and EMI suppression. Metal shielding and thermal pads integrated into the mechanical assembly provide both electromagnetic containment and efficient heat dissipation. This sophisticated, modular construction enables high-frequency operation, robust performance, and ease of manufacturing or service, reflecting the design priorities of a modern omnidirectional radar system.
High-Frequency RF Front-End PCB
A close-up of one of the internal PCBs showcases the precision engineering behind the radar’s RF front-end and signal processing subsystems. This section features several integrated circuits in compact QFN packages, densely grouped to form specialized functional clusters—most likely radar transceivers, low-noise amplifiers, and analog/mixed-signal chips essential for high-frequency signal manipulation. The black solder mask and gold ENIG finish not only enhance durability but also optimize high-frequency performance by reducing signal loss. The board’s layout includes wide, curved traces with controlled impedance, designed for microwave signal routing, and extensive ground pours with stitching vias to minimize EMI and preserve signal clarity. While no discrete antenna elements are visible here, the trace geometry strongly suggests these are RF feedlines leading to the main antenna array or connectors. The absence of large connectors in this section points to its role as an RF subassembly, with critical signals routed via high-speed board-to-board or FPC connections. This PCB exemplifies the meticulous attention to RF design and modularity necessary for a high-performance, compact radar sensor.
Planar Patch Antenna Array PCB
The antenna-side PCB is a standout example of advanced RF engineering, featuring an array of gold-plated square patches that form the core of the radar’s omnidirectional sensing capability.
