Abstract: Methods, systems, and devices for channelizing and beamforming a wideband waveform are described. Generally, the described techniques provide for transmitting and receiving wideband waveforms that are beamformed on a per-channel basis during generation of the wideband waveforms. A transmitter may separate a first wideband signal into segments, with each segment bandwidth corresponding to a channel of the system bandwidth, and may map the segments to channels. The segments may be replicated to generate multiple copies of each segment. The transmitter may beamform and combine the copies of the segments to generate multiple wideband waveforms, and transmit each wideband waveform using a different antenna. A receiver may receive multiple wideband waveforms using multiple antennas and may separate each wideband waveform into segments, then beamform and de-map the segments. The techniques may be used to transmit and receive beamformed wideband waveforms over tactical data links.

Abstract: Methods, systems, and devices for channelizing a wideband waveform for transmission on a spectral band comprising unavailable channel segments are described. Generally, the described techniques provide for transmitting and receiving wideband waveforms when channels of a system bandwidth are unavailable for transmission. A transmitter may separate a first wideband signal into segments, with each segment a bandwidth corresponding to a channel of the system bandwidth, and may map the segments to the available channels. The transmitter may combine the mapped segments into a second wideband waveform and transmit the second wideband waveform using the available channels. A receiver may receive a first wideband signal waveform and may separate the first wideband signal waveform into segments, de-map the segments and combine the de-mapped segments into a second wideband waveform for demodulation. The techniques may be used to transmit and receive wideband waveforms over tactical data links.

Abstract: Systems and methods for a scalable architecture for radio device and systems are disclosed. This architecture employs a scalable bandwidth to deliver higher data rates and transmission ranges to devices that need them, while still delivering lower power solutions for devices which utilize a smaller bandwidth. These systems and methods may divide the available frequency spectrum into a set of fundamental sub-bands. Different devices may use various multiples of these sub-bands depending on their needs. Devices employing this architecture are also capable of interoperation with one another regardless of the bandwidth they utilize. A device may scan through each sub-band within which the device intends to operate, searching for a common beacon transmitted by other devices utilizing the sub-band. If a beacon is found the device can choose to interoperate with the other device or, alternatively, continue scanning the sub-bands until an unused sub-band is found.

Photolithography and electroless plating were used to create well-defined conductive areas on the LTCC ring electrode. The inventive method allows for the precise control of establishing conductive areas on a non-conductive substrate through the steps of punching, lamination, firing, metallization and photolithography on the metallized layer.
