I coordinate a design team for the realization of a device that includes an RF section but in the group we have limited knowledge of RF design. In particular I need to make a Class E RF amplifier with the following characteristics: • operating frequency 406.0 MHz • power 5W (37dBm) • TX duty cycle 10ms (transmission time 500 ms every 50 s) • 7.2Vdc power supply • input power 100mW (20dBm) • two-phase modulated input signal • input impedance 50Ω • output impedance 50Ω • efficiency ≥ 70% • operating temperature between -20 and +55 • the output power must go from 10% to 90% of the max power in less than 5ms • must work with VSWR between 1: 1 and 3: 1 • must not be damaged if the load is shorted or open • must be made with SMD components • preferred amplifier component (without constraint): AFT09MS007NT1 I am looking for an RF circuit designer who is able to assist me in the realization of this circuit and who can provide me with schematics, formulas and PCB layout to allow me to create the device (PCB realization, components, assembly and tests will be in my care).

Salve, Sono un ingegnere elettronico e delle telecomunicazioni e la mia specializzazione è wireless systems' design. Ho esperienza nella progettazione di hardware e sistemi embedded. Ho progettato/stampato/testato molti PCB e ho una certa esperienza con la progettazione RF come la progettazione di antenne, reti di abbinamento (elementi distribuiti/lumeggiati), filtri (elementi distribuiti/lumeggiati), amplificatori di potenza, divisori, reti di alimentazione, coppie differenziali/ segnali, EMI, aree libere, schermatura per EMI, interferenza condotta, modo comune, ecc., LVD, comunicazione dati ad alta velocità. Ho verificato le tue esigenze, ho disegnato un amplifier per COSPAS per 406.025MHz. Sono abbastanza sicuro di poterti aiutare con il tuo progetto. Dammi solo tutti i dettagli e farò del mio meglio per aiutarti. Cordinali saluti

Good day, I have deep knowledge in electronics designing and I can design Class E RF amplifier with 7.2Vdc power supply and operating frequency 406.0 MHz and I will be done this project according to your all requirements. I would like to have a thorough discussion on this project as there are certain suggestions from my side After dedicating more than 30 years to the electronics design and development, I am passionate in designing the best products Technology wise I have worked on all the latest technologies like GSM, 5G, Lora, Class E RF Amplifier, 406.0 MHz, DC Power Supply etc And have worked on more than 20 design tools for designing and simulation purpose Some of the generic queries from my side are: 1. What is the application of this product? 2. What will be the ambient temperature of this product? 3. What are the mechanical constraints to be taken care of? If you are someone who wants to benefit from my experience just message me Hi and I shall be there for you  Regards Hari Mohan Engineering for one is magic for others
