US 2026/0088786 A1 · Multipath Amplifier Circuitry with Compact Transformers

Abstract

Wireless circuitry may include multipath amplifier circuitry with a first amplifier on a first path and a second amplifier on a second path. The first and second paths may be coupled between an input and output networks. The input network, the output network, and/or an inter-stage matching network may include a transformer circuit. The transformer circuit may include a first transformer on the first path and a second transformer on the second path. The first transformer may overlap the second transformer on a substrate. The first transformer may be orthogonal to the second transformer such that current on the first transformer does not induce current on the second transformer and vice versa. This may serve to minimize the area consumed by the multipath amplifier circuitry while also preserving isolation between the first and second paths.
