EnmobiX Redefines the W-Band Passive Imaging Market with a Single-Chip Silicon Solution

Share Article

EnmobiX has introduced ENX9401, a silicon single-chip solution for W-band passive imaging applications. It integrates all necessary functions (mmWave to baseband) for a passive imaging system at a fraction of the power consumption and cost, compared to existing industry solutions.

EnmobiX has announced the availability of the ENX9401, a silicon-based single-chip solution for W-band passive imaging. In addition to the basic blocks of LNA, power detector, integrator, and amplification, ENX9401 incorporates patent-pending techniques to cancel the flicker noise and self-biasing noise, exceeding the performance of current III-V solutions in the market.

Passive imaging works based on the blackbody radiation. Objects with higher temperatures or higher reflectivity radiate at higher power levels. A passive imaging pixel receiver detects the radiated power from a limited area (pixel) it is focused on. By putting the information from adjacent pixels together, a 2-D picture can be formed. The main advantage of W-band for passive imaging systems is the fact that W-band signals are transparent to dust, rain, mist, clothes, etc. Therefore, W-band imagers can be used for concealed weapon detection and detection under poor visibility conditions.

“Current solutions in the market are based on multiple dice using exotic III-V processes like GaAs and InP. The high price and high power consumption of these solutions has forced the system manufacturers to use scanning arrays and delicate mechanical scanning systems, resulting in further increase in cost, size and weight of the system. ENX9401 is the first silicon single-chip solution which can exceed the performance of III-V solutions by enabling NETK<0.1°K at a fraction of power consumption of other existing solutions. Several key inventions were needed for this breakthrough to be possible,” said Farbod Behbahani, CEO of EnmobiX. “Compared with existing solutions, ENX9401 enables passive imaging manufacturers with simpler, more reliable, lower cost, smaller, and lower power consumption systems. Our solution will also enable commercial implementation of innovative system architectures that, so far, were only limited to research.”
