550 W L-Band LDMOS Amplifier Pallet Under Test

Initial bench tests produced more than 550 W from 1.2 to 1.4 GHz, with over 600 W at saturation and 20 dB gain before tuning.

Initial bench testing of E-REON's new L-band amplifier pallet produced more than 550 W across 1.2 to 1.4 GHz without tuning.

At saturation, the pallet delivered more than 600 W with approximately 20 dB of gain.

Integrated control and protection

The design includes temperature-compensated bias and an onboard temperature sensor with a buffered analogue output that varies linearly with temperature. An overtemperature alarm output provides additional protection.

A dedicated trigger input supports noise quieting when required by the host system.

LDMOS platform and production readiness

The pallet is based on a mature generation of Ampleon LDMOS technology and is intended for high-power pulsed L-band applications.

Following the initial test phase, the design was being prepared for serial production in the first quarter of 2026.
