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.
IP knowhow
The true value in a custom RF PA lies in the sophisticated integration of specialized knowledge and IP blocks. Unlike other IC design houses, we don’t insist on using our own IP blocks. Instead, we choose the best option to meet your needs.

FAQ
get ahead with your own custom silicon
Explore Bruco IC's comprehensive design services, from system specification to qualified silicon, ensuring seamless product lifecycle management.
The Non-Recurring Engineering (NRE) costs vary significantly based on complexity (e.g., analog vs. digital content) and the chosen process node. A feasibility study is the only way to get a precise estimate, but general estimates for high-end RF ASIC design start in the mid-six figures, covering design, verification, masks, and initial wafers.
A typical full-cycle project takes approximately 18 to 24 months. This includes 6-8 months for architecture/design, 4-6 months for fabrication (tape-out to first silicon samples), and 4-8 months for validation, characterization, and final qualification (RFS milestone)
We offer flexible engagement models. While we excel at full turnkey ASIC solutions, our engineers frequently integrate with R&D teams, providing specialized expertise in high-frequency design, complex block implementation (like PLLs or high-speed ADCs), or deep verification support (UVM).
As a fabless house, we use the best technology for your spec. For high-performance RFICs, we often utilize SiGe BiCMOS or advanced CMOS nodes (down to 22nm) for optimal balance of speed and power, working with leading foundries like Global Foundries, TSMC, and Tower/Jazz.
All custom design intellectual property developed specifically for your project is owned by you. We implement robust security protocols and can integrate standard or custom security IP cores (e.g., AES, ECC/ECDSA) directly into the silicon to protect your valuable algorithms and data.
Post-production support is included as part of the supply chain management, covering long-term logistics, buffer stock agreements, yield monitoring, and obsolescence management. We ensure your product remains reliably available throughout its full commercial lifecycle.
