    IPC: H04B1/40

    CPC classification number: H04B1/40

    Abstract: A transceiver includes a radio frequency (RF) input, an RF channelized digital receiver, an RF wideband digital receiver, an analog-to-digital converter (ADC)/digital-to-analog converter (DAC), an RF channelized digital transmitter, and an RF output. The RF channelized digital receiver is configured to split an analog RF input signal into a plurality of sub-octave contiguous frequency band channels and to convert the channels to a plurality of first digital signals. The RF wideband receiver is configured to convert the analog RF input signal into a second digital signal. The ADC/DAC is configured to process each of the first and second digital signals to produce a plurality of third digital signals. The RF channelized digital transmitter is configured to convert each of the third digital signals into a plurality of analog output signals, to combine the analog output signals into an analog RF output signal, and to transmit the analog RF output signal.

    Abstract: A cavity backed antenna assembly includes a conductive lower wall and two or more conductive side walls at least in part defining a cavity. The antenna assembly further includes a first layer and a second layer each including a first dielectric material above the lower wall and within the cavity, and a third layer including a second dielectric material between and separating the first and second layers. In an example, the second dielectric material compositionally different from the first dielectric material. The antenna assembly further includes a first conductive structure and a second conductive structure separated by a third dielectric material, wherein the first conductive structure and the second conductive structure are within the cavity and above the first and second layers. In an example, the first dielectric material a relative magnetic permeability of at least 1 for a frequency between 10 MHz and 1 GHz.
