Irvine, California – 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 patented 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 temperature or higher reflection coefficient radiate at with higher power. Passive imaging pixel receiver detects the radiated power from a limited area (pixel) it is focused on. By putting the information for adjacent pixels, a 2-D picture will be formed. The advantage of W-band for passive imaging systems is the fact that W-band signals pass through dust, rain, mist, cloths, … Therefore, the system can be used to detect concealed weapons and detection under poor visibility condition.
“Current solutions in the market are based on multiple dice using III-V processes like GaAs and InP. The high price and high power consumption of these solution has forced the system manufacturers to use scanning arrays and delicate mechanical scanning systems, resulting in further increase of 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<0.1K at a fraction of power consumption of other existing solutions. Several key inventions were needed for this breakthrough to be possible,” says Farbod Behbahani, CEO of EnmobiX. “Compared with existing solutions, ENX9401 enables passive imaging manufacturers with a simpler, more reliable, lower cost, smaller, and lower power consumption systems. In short, it will redefine the market.”
