ReviewerIEEE MWTL

I'm an RF design engineer in Irvine, California, leading module development at Skyworks Solutions. My day-to-day lives in RF front-end modules — the analog edge where a radio meets the air, increasingly reaching past the cell tower to non-terrestrial networks.

I lead designs from architecture through System-in-Package integration and into production silicon. Lately I've been working in two directions: FR3 mid-band front-ends, and integrated sensing and communication (ISAC), where the same hardware that carries data can also perceive the world around it.

Outside the lab I chair the IEEE MTT-S Orange County chapter, review for IEEE Microwave and Wireless Technology Letters, and speak on where the RF front-end is headed.

What I work on

/ RFFE

Front-End Modules

Multi-function RFFE design and the layout, isolation, and thermal calls that decide whether a module ships. My core work.

/ ISAC

Sensing & ISAC

Integrated sensing and communication — radios that detect and locate while they carry traffic. Where I'm heading next.

/ FR3

FR3 Mid-Band

Pushing front-end techniques up into the FR3 mid-band, where coverage and capacity have to coexist.

/ NTN

Non-Terrestrial Networks

Front-end design for direct satellite-to-device links — the bands, link budgets, and sensitivity that NTN demands.

/ SiP

SiP Integration

System-in-Package assembly: bringing filters, dies, and passives into a footprint that survives manufacturing.

/ PKG

Packaging & Size Reduction

Shrinking RFFE modules through filter stacking and package architecture — the subject of three pending patents.

Non-terrestrial front-ends

NTN · Direct-to-device

Extending RF front-end design toward non-terrestrial networks — the link budgets, sensitivity, and band coverage that direct satellite-to-device connectivity puts on the front-end.

ISAC · Research direction · Ongoing

A research thread on sensing-aware front-end design for ISAC — radios that detect and locate while they carry traffic. Bridging the modules I ship today and the perceptive systems coming next.

Today's silicon ships in the sub-GHz bands. The research lives an order of magnitude up, in FR3 — the deliberate stretch from one to the other is the point.
