the Challenge

Doherty Power Amplifier Application design

Does the success of your next product in the communication or industrial market hinge on the requirement for high power and superior efficiency? Designing a powerful RF Power Amplifier (PA) ASIC (1W to 1000W) requires in-depth knowledge of Doherty PA architectures and advanced technologies like LDMOS and GaN.

For more than ten years Bruco IC has a broad and in-depth experience in and knowhow of Doherty Power Amplifier (DPA) application designs. Typically the Doherty Power Amplifier Application design is applied for Cellular Base stations. A dedicated design is made to match the requirements from the end customer and the involved Power Amplifier Over 100+ DPA designs completed successfully using LDMOS and GaN transistor technology.

Mastering Front-end RF

Our engineers master the complex architecture required for high-end Power Amplifier systems. We deliver the full amplifier solution, including the Driver stage, Pre-stage, and the Doherty PA module

System-Level Integration

We seamlessly integrate the IC design and perform 3D EM modelling. This ensures the chip function as one optimized system, crucial for high-power RF applications

In-house Test Lab & Load-Pull

Bruco IC has its own RF test lab to support tuning and characterization (0.7–4 GHz). This includes load pull measurements , which are essential for optimizing the amplifier for maximum efficiency and linearity under various loads.

Mechanical Prototyping

We maintain an in-house mechanical lab for manufacturing and soldering of baseplates and inserts, which significantly increases throughput speed and adaptability during the prototyping phase

Our network

the most suitable technology for each application

Unlike an IDM (Integrated Device Manufacturer), we are not tied to our own factory. As an independent, fabless design house , we select the most suitable process technology and node to achieve your specific power and frequency targets. Do you want the full overview of our network and IP knowhow? We recommend contacting us or downloading our corporate brochure for a brief overview.

Processes & Nodes

We focus on the most robust and efficient processes to support the power range of 1W to 1000W.

GaN (Gallium Nitride)
Utilized for applications demanding extremely high power density, high frequencies, and superior efficiency. It is the ideal choice for applications like 5G base stations, radar, and satellite communication.

LDMOS (Laterally Diffused Metal Oxide Semiconductor)
Proven technology for high power amplification within the frequency band of 0.1 to 4 GHz. It ensures reliability and performance under heavy load.

Our Proven design approach for high-quality ASICs

Every phase of our IC development is meticulously engineered to uphold the exceptional standards our clients demand. From initial concept through final delivery, ensuring that each custom ASIC we produce meets the most stringent performance criteria.

01.

Feasibility & Architecture

Start analyzing the technical challenges and risks with a feasibility study. We  cooperate closely during this phase to understand not just the IC requirements but also how the ASIC should function inside the application. This will tell us what requirements are really important, and what are the nice-to-haves. As an independent (fabless) design company, we choose the best process technology (plain CMOS, BCD, RF-SOI or SiGe) based solely on your needs plus clear technology roadmaps and budget constraints. The end result is not a prototype, but a detailed technical report with a proposed architecture and clear agreed, specifications of underling IP blocks, along with NRE projections for the entire development. This serves as a 'go/no-go' input depending on the business case.
 
This phase typically takes 2 to 4 months depending on the complexity of your ASIC requirements.

02.

Circuit Design & Verification

The "first-time-right" circuit design starts after the concept has been validated. Using advanced EDA tools and proven methodologies, we optimize every circuit element for your specific performance, power, and area requirements.
Our experienced IC engineers manage trade-offs between functionality, cost, and manufacturability while ensuring your ASIC meets all technical specifications.

Throughout development, we work closely with your team, providing regular design reviews and milestone updates. This phase typically takes 12 to 24 months.

VERIFICATION & TESTING

Before your ASIC reaches production, rigorous verification are essential to ensure a flawless operation across all conditions. Our testing methodology combines advanced simulation environments with comprehensive test vector development, validating functionality, timing, and edge-case scenarios.

Physical prototypes undergo extensive characterization including parametric testing, stress analysis, and environmental qualification. We verify performance margins, identify potential failure modes, and confirm compliance with your specifications.This thorough validation process eliminates costly surprises during production ramp-up. Every test result provides confidence that your ASIC will perform reliably in real-world applications, meeting both technical requirements and market expectations.
