Patent Overview: US 8,630,601 B2 — "Active Channelized Integrated Antenna System"
Bibliographic data (from the supplied text): US Patent 8,630,601 B2; application US 12/384,490; filed 2009-04-06; granted/publication date 2014-01-14; priority date 2009-04-06; inventors Charles Chandler, Roger A. Conrad, and Robert A. Deaton; original and current assignee Raytheon Company. The listed status is Active with an adjusted expiration of 2030-09-22 (the source notes legal status is an assumption, not a legal conclusion). Related publications include US20100255805A1, IL204865A, and EP2239859A3.
Purpose: The patent addresses broadband electronic warfare (EW) antennas, which are often mounted on aircraft wingtips and rear vertical stabilizers and connected to host receivers by long coaxial cables. Cable losses vary with frequency and add to receiver noise figure; radome-integrated EW antennas may not maximize aperture area; and broadband amplifiers handling high input signal levels introduce harmonics and inter-modulation products that could be mistaken for real signals. The disclosed system seeks to receive a signal with any polarization over a wideband spectrum, amplify it without introducing significant harmonics, and retransmit the full band to a remote location.
Plain-language scope: An antenna array operates over a multi-octave band. An electronics module near the antenna divides the received spectrum into frequency-band components each less than an octave wide (channelization), amplifies each with a respective low-noise amplifier of less than an octave bandwidth, and combines the amplified components into a composite signal. A transmission medium — coaxial cable, fiber optic line, or free space — carries the composite signal to a remotely located receiver. Embodiments tune nested antennas to specific bands (e.g., 1–1.8 GHz, up to 22–40 GHz), use a demultiplexer to split a band, and employ baluns, limiters, couplers, switches, noise generators for calibration, and spiral/sinuous antennas on a segmented aperture conformal to a radome.
What the excerpt does not establish: It does not provide claim text, the full specification, drawings' details, prosecution history, or any prior-art analysis, and it does not substantiate the legal status or expiration date.

Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
