ANALOG PREDISTORTION FOR E-BAND
Unlocking Usable Output Power at mm-Wave
E-band systems are increasingly limited not by peak power, but by linearity under wide bandwidth and high-order modulation. Gotmic AB offers an on-chip Analog Predistortion (APD) solution designed specifically to address this bottleneck in real E-band transmitters.
The Problem APD Solves at E-band
In high-capacity E-band links:
force power amplifiers to operate with significant back-off. The consequences:
Gotmic’s APD Approach
Linearization in the RF domain. Gotmic’s APD:
Unlike digital predistortion:
Tunable, Adaptable, and Practical
The APD platform is designed to adapt to process variation, temperature drift, frequency of operation, and different modulation formats. Control parameters allow for optimization of linearity vs efficiency, re-tuning in production or deployed systems, and maintaining performance over the lifecycle.
System-Level Impact
Using APD in an E-band transmit chain enables:
Typical Applications
DESIGN FOR THROUGHPUT. NOT BACK-OFF.

ANALOG PREDISTORTION FOR W-BAND
Enhancing Linearity and Dynamic Range in Radar Front-Ends
Linearization where radar systems need it most. W-band radar systems are increasingly constrained by PA non-linearity, AM-PM distortion and reduced dynamic range under real operating conditions. Gotmic’s Analog Predistortion (APD) provides a new tool to address these challenges directly in the RF domain.
Why linearization matters in W-band radar
In radar front-ends:
These effects directly influence:
Benefits of APD
Better radar performance without increasing hardware complexity. Using APD in W-band radar front-ends can:
APD for Radar-Centric Architectures
Gotmic’s APD is integrates naturally into radar transmit chains, supporting, FMCW radar, pulsed radar, and advanced modulation or coded waveforms. The APD:
Complementary to Radar Calibration
APD does not replace radar calibration—it reduces its burden. By stabilizing PA behavior calibration becomes more predictable, sensitivity to temperature and bias drift is reduced and system margins improve.
Typical Applications
Improve radar performance without redesigning your PA.
