@SidUSA

Hi, We are available to take this on and get your RF amplifier circuit working perfectly. The main issue with high-frequency designs in the 3 GHz to 30 GHz range is often maintaining stability and linearity while managing thermal constraints. Are you planning to use simulation tools like ADS or HFSS for the initial modeling phase, and do you have specific requirements for the bandwidth and gain flatness across the 1W to 10W output power range? We recently completed a similar RF project for a communications firm that required high-frequency amplification within a tight form factor. We utilized HFSS to model the layout and performed rigorous stability analysis to ensure performance met the specified output levels. We also optimized the matching network to handle the high-frequency transitions, which prevented signal degradation during testing. Our approach ensured the circuit was stable, efficient, and ready for fabrication. We are eager to discuss the project further. Reach out to initiate a conversation! Best regards, Quantum Code Solutions
