Abstract: An apparatus includes a via-fed dual-polarized patch, a first capacitive-fed dual-polarized patch, and a second capacitive-fed dual-polarized patch. The first capacitive-fed dual-polarized patch is capacitively coupled to the via-fed dual-polarized patch through an air gap. The second capacitive-fed dual-polarized patch is capacitively coupled to the first capacitive-fed dual-polarized patch through a dielectric layer.

Abstract: A radio frequency (RF) unit and a method for RF isolation. The RF unit includes first and second RF couplers, an RF filter, and an RF canceler connected in parallel with the RF filter. The first RF coupler is configured to receive an input signal. The RF filter is configured to receive a first portion of the input signal from the first RF coupler and attenuate frequencies outside of a passband of the RF filter from the first portion of the input signal. The RF canceler is configured to receive a second portion of the input signal from the first RF coupler and generate a cancellation signal from the second portion of the input signal based on a target frequency band of the RF canceler. The second RF coupler is configured to combine the cancellation signal with an output of the RF filter to generate an output signal.

Abstract: Methods and apparatuses for facilitating wide bandwidth power amplification with high efficiency for analog RF signals. A passive load modulated balanced amplifier (LMBA) device comprises a balanced power amplifier (BPA) and a directional coupler. The BPA comprises a first power amplifier (PA) configured to amplify a first portion of an input power, a second PA configured to amplify a second portion of the input power, an isolation port, and an output port that outputs the amplified first and second portions of the input power as an output power. The directional coupler is configured to provide a portion of the output power from the output port to the isolation port to modulate a load impedance of the first and second PAs.
