The first feature of these modules is the adaptation of the redistribution layer (RDL) process, which has achieved high-density and high-precision antennas in packages (AiP) integrated with RFIC. The second feature is double patch antennas with cavities for high-gain antennas. We designed …

We propose a low-loss, high-heat dissipative fourway power combiner that can be applied to multiple monolithic microwave integrated circuits (MMIC) with flip-chip bonding for high power solid-state power amplifier modules. This structure mainly consists of a two-way power combiner comprising an air-filled …
