Signal isolation for module with ball grid array. In some embodiments, a packaged module can include a packaging substrate having an underside, and an arrangement of conductive features implemented on the underside of the packaging substrate to allow the packaged module to be capable of being mounted on a circuit board. The arrangement of conductive features can include a signal feature implemented at a first region and configured for passing of a signal, and one or more shielding features placed at a selected location relative to the signal feature to provide an enhanced isolation between the signal feature and a second region of the underside of the packaging substrate.

In an embodiment, an apparatus includes a first radio frequency (RF) signal path and a second RF signal path. The first RF signal path can provide a first RF signal when active and the second RF signal path can provide a second RF signal when active. The second RF signal path can include a matching network with a load impedance configured to prevent a resonance in the second RF signal path due to coupling with the first RF signal path when the first RF signal path is active.

Multi-band device with reduced band loading

A coupler is presented that has high-directivity and low coupling coefficient variation. The coupler includes a first trace with a first edge substantially parallel to a second edge and substantially equal in length to the second edge. The first trace includes a third edge substantially parallel to a fourth edge. The fourth edge is divided into three segments. The outer segments are a first distance from the third edge. The middle segment is a second distance from the third edge. Further, the coupler includes a second trace, which includes a first edge substantially parallel to a second edge and substantially equal in length to the second edge. The second trace includes a third edge substantially parallel to a fourth edge. The fourth edge is divided into three segments. The outer segments are a first distance from the third edge. The middle segment is a second distance from the third edge.

In an embodiment, an apparatus includes a first radio frequency (RF) signal path and a second RF signal path. The first RF signal path can provide a first RF signal when active and the second RF signal path can provide a second RF signal when active. The second RF signal path can include a select switch having an input shunt arm electrically coupled to an input of the select switch. The input shunt arm can be arranged such that it is on when the first RF signal path is active and/or when the second RF signal path is inactive.

A coupler is presented that has high-directivity and low coupling coefficient variation. The coupler includes a first trace associated with a first port and a second port. The first trace includes a first main arm, a first connecting trace connecting the first main arm to the second port, and a non-zero angle between the first main arm and the first connecting trace. Further, the coupler includes a second trace associated with a third port and a fourth port. The second trace includes a second main arm.

Reducing coupling coefficient variation by using angled connecting traces

A coupler is presented that has high-directivity and low coupling coefficient variation. The coupler includes a first trace associated with a first port and a second port. The first port is configured substantially as an input port and the second port is configured substantially as an output port. The coupler further includes a second trace associated with a third port and a fourth port. The third port is configured substantially as a coupled port and the fourth port is configured substantially as an isolated port. In addition, the coupler includes a first capacitor configured to introduce a discontinuity to induce a mismatch in the coupler.
