Is There a Moore's Law for RF?
Four decades of transistor records suggest the field has been following a trend it never named.

I work at the edge of what radio can do, and then I build the institutions the work needs. The millimeter-wave hardware became two US patents and a Gold Medal in Geneva. The research society and journal I founded take more than two hundred young engineers from a first question to a finished result. One question runs through all of it, from RF into chips and AI: how fast can a technology actually improve?
What I work on
The research record
Hardware
Millimeter-wave and terahertz hardware
Transitions, interconnects and on-chip antennas from 30 to 350 GHz. The patented transition was measured from 50 to 75 GHz with less than a quarter of a decibel lost.
Antennas
Arrays for satellites, drones and air taxis
Air-filled multi-beam arrays on rigid-flex boards, four tilted beams across the V-band at 15.5 dBi, built for urban air mobility and low-orbit links.
Measurement
From the simulator to the bench
Anechoic chambers, network analysers and machined prototypes: the part of the work that decides whether the simulation was right.
Scaling
Chips, AI and how technology improves
Moore's Law for RF, the three mechanisms behind AI compute, and which ceiling arrives first.

Notes
Building a Network Now Costs Less Than Buying One
Community fibre and low Earth orbit satellites are the same story.
Notes
A Simulation Is a Promise
Moving a millimeter-wave transition from equations to a patented prototype.
AI & Computing
How AI Scales, and What Stops It First
Break training compute into its three mechanisms and the first ceiling is the grid, not the chips.
RF & 6G
Why Hardware Is the Hard Part of 6G
The systems 6G promises rest on connections you cannot see.
The Engineering Profession
The New RF Engineer
What the job looks like when the tools start doing the middle of it.
Moore's Law for RF
Four decades of RF transistors, one straight line.
The record speed of RF transistors has climbed about 1.6× per decade since 1985, in jumps and long plateaus, and the frontier points to three more jumps by 2050.

Engineer, inventor and founder. RF, chips, AI, and how technology scales.
The bench where it started, the people I build things for, the question I cannot put down, and where it is all going.
