The current civilian Doppler microwave sensors operate in C-band (5.8GHz), X-band (10.525 / 10.687GHz) and K-band (24.125GHz), with transmit power less than 10 mW. These frequencies are specified in the ITU ISM band and do not require frequency use applications. Detection patterns include omnidirectional and directional options, with ranges from 0.1 to 50 meters depending on antenna gain and transmit power.

Microwaves emitted by the transmitting antenna are absorbed or reflected by encountered objects, causing power changes. The receiving antenna converts reflected microwaves into electrical signals for processing by measurement circuits, enabling microwave detection.

A microwave PCB is a specialized circuit board designed for microwave devices and systems, optimized for high-frequency signal handling.

• High-Frequency Design: Engineered for 300 MHz to several GHz range with minimized signal loss and controlled impedance
• Material Selection: Uses specialized substrates like ceramic-filled PTFE (Rogers, Taconic, Arlon) with low dielectric loss
• Controlled Impedance: Critical for signal integrity, using precisely designed traces and transmission lines
• RF Connectors: Incorporates high-performance connectors (SMA, SMP) for minimal signal loss
• Grounding/Shielding: Advanced techniques to minimize noise and electromagnetic interference

Microwave PCBs are essential in radar systems, satellite communications, wireless networks, and high-frequency test equipment. Their design requires specialized expertise in high-frequency electronics.
