Custom Doherty Power Amplifiers

The challenge for Telcom is to design base station amplifiers that offer more power and higher efficiency, while remaining compact and thermally efficient. We have the deep, hands-on expertise to design and build high-efficiency Doherty PAs across multiple frequency bands (700MHz to 3GHz) and at high power levels (up to 1kW).

Custom Doherty PAs for 5G Base Stations

The challenge for Telcom is to design base station amplifiers that offer more power and higher efficiency, while remaining compact and thermally efficient. Speed to market is important, but not at the expense of performance. Bruco IC helps you overcome this challenge. We provide complete, turnkey development of efficient Doherty Power Amplifiers (PAs). We guide your project from the initial design to a fully validated and characterized demo board—faster and more reliably than managing multiple suppliers.

Our Solution: An Integrated, In-House Process

We have the deep, hands-on expertise to design and build high-efficiency Doherty PAs across multiple frequency bands (700MHz to 3GHz) and at high power levels (up to 1kW).

What makes our process different:

Complete Electrical & Mechanical Build: We don't just deliver a design file; we deliver functional hardware. Our team handles the complete electrical design, layout, and assembly.
In-House Mechanical Workshop: Critical mechanical parts, like custom heatsinks and mounting brackets, are fabricated in our own shop. This eliminates delays from outside vendors and ensures a perfect thermal and physical fit from day one.
Advanced In-House RF Lab: We measure, tune, and characterize the complete Doherty amplifier in our own state-of-the-art lab. This allows for rapid optimization and guarantees the hardware you get performs exactly as simulated.

For leading customers in the telecom sector, we continuously produce Doherty demo boards to validate their newest LDMOS devices. The challenge is always the same: create a physically compact design in a short timeframe, while achieving maximum electrical efficiency and output power.

The Benefit of Our In-House Process

Faster Time-to-Market: Our all-in-one process (design, mechanical, test) cuts out vendor bottlenecks and delivers a validated design faster.
Real High-Power Expertise: You get a team that has deep, practical experience with the newest LDMOS and GaN devices and complex PA architectures.
No Surprises, Just Working Hardware: You receive a fully-functional, characterized demo board, not just a simulation. It's hardware that is ready for your system integration and testing.
An Extension of Your Team: We work like an extension of your R&D team to find the right, practical balance between performance, cost, and form factor.
