Solving the "High Power, Small Size" Challenge in 10–13 GHz Band – New 100W Amplifier Module for Radar and Satellite Communication Systems

Why 10–13 GHz Matters

The 10–13 GHzfrequency range covers critical portions of the X‑band, widely used in airborne radar, marine navigation, satellite communication (SATCOM), and electronic countermeasure systems. Systems operating in this band require amplifiers that not only deliver high output power but also maintain linearity, low spurious emissions, and stable performance under harsh environmental conditions.

What Sets This Module Apart

At the core of this module is a GaN‑based design that achieves 50 dBm (100W) typical output power and 50 dB typical power gain across the full 10–13 GHz band, with gain flatness within ±2 dB. Unlike conventional amplifiers that often compromise either size or performance, this module fits into a 140×130×27.5 mm enclosure and weighs less than 1.2 kg — making it suitable for space‑constrained platforms such as UAVs, ground terminals, and portable radar systems.

The module supports CW, pulsed, and various RF modulation signals, offering flexibility for both continuous transmission and pulse‑based radar operations. Spurious emissions are kept below -60 dBc, ensuring clean spectral output — a critical requirement for sensitive receiver co‑location.

Built‑in Protection for Mission‑Critical Reliability

Field deployment often comes with unpredictable power conditions and environmental stress. This amplifier incorporates multiple layers of protection:

• Over‑voltage, over‑current, and over‑temperature protection – automatically shuts down or limits output under abnormal conditions.

• Over‑excitation tolerance – withstands input power up to +10 dBm without damage.

• Reverse polarity protection – prevents damage from accidental power supply reversal.

• Wide‑range enable control (5V–28V) – compatible with various control logic levels.

The module is rated IPX5 for water resistance, ensuring reliable operation in rain‑exposed environments — a feature rarely found in amplifiers of this power class.

Thermal Design That Works

Thermal management remains the biggest hurdle for 100W‑class amplifiers in the 10–13 GHz band. This module achieves a typical efficiency of 30% with an operating voltage of 32V, striking a balance between output capability and heat dissipation. The housing combines 6061 aluminum alloy and T2 electrolytic copper, with a hybrid surface finish — electroless nickel plating combined with natural‑color conductive anodization — ensuring both corrosion resistance and good heat conduction.

Interface and Integration Flexibility

Designed for straightforward system integration, the module features:

• RF input: N‑Female

• RF output: WR75 (BJ120) waveguide interface

• Power and control: J30JM‑15ZKP connector with defined pin‑out for easy control integration

The amplifier can be switched on/off via a manual button or external TTL‑level PAEN control, giving system designers both local and remote control flexibility.

For system integrators working on X‑band radar, SATCOM ground stations, or electronic warfare systems, the 10–13GHz 100W Power Amplifier Module offers a drop‑in solution that delivers power density and reliability in a compact form factor. It is now available for sampling and integration testing.
