Abstract
Microwave-induced thermoacoustic (TA) imaging,
combining high microwave contrast with high ultrasonic res-
olution has the potential to revolutionize applications such as
continuous healthcare monitoring, point-of-care imaging, and
biometric authentication. However, the size, cost, and integration
of a high-power microwave transmitter is a key bottleneck in
making TA imaging truly portable, affordable, and ubiquitous.
Toward that end, this work presents a compact 4.9-GHz pulsed
power amplifier (P
