integration. GaAs optimizes linearity for
front-end amplification; GaN delivers
high power density; silicon excels
at complex control and digital logic.
Instead of placing these dies next to
one another on a board, 3D integration
stacks and vertically interconnects them
using technologies such as system-inpackage (SiP), through-silicon vias
(TSVs), and advanced interposers.
The benefits are real and measurable:
• Greater interconnect efficiency:
Microscale vertical vias replace
millimeter-long traces, cutting
interconnect power consumption by
30–50 %.
• Significant SWaP reduction: A
stacked 3D RF module can shrink
system footprint by 60% or more—a
vital advantage for satellites and
beamforming arrays.
• Improved signal quality: Shorter
electrical paths reduce insertion
loss and noise, boosting overall link
performance.
This trend validates Circuits
Integrated’s focus on tightly integrated
GaAs antenna-in-package (AiP)
solutions. While GaAs remains the superior choice for high-efficiency, linear
amplification in dense phased arrays,
its full potential is only unlocked when
it is tightly integrated—vertically—
with silicon control layers. In the race
toward 2026 and beyond, success
won’t come from the best standalone
transistor: it will come from the best
architected, vertically integrated RF
system. The era of discretes is giving
way to the era of 3D integrated RF.
