Design and development of a 30 kW, 352 MHz pulsed RF solid-state power amplifier to be utilized for feeding re-bunching cavities in proton linac, is in progress at ESS-Bilbao. This modular transmitter is based on in-phase combination of compact, water-cooled 2 kW RF power modules, each one consists of two combined LDMOS transistors in balanced configuration. The modules include individual bias control, measurement and supply circuits. Gate modulation is foreseen to increase efficiency in pulsed regime that is up to 3ms RF pulse width and 10% duty cycle. The 2 kW RF power module has been developed and the test results are discussed.

In order to test both the design and manufacturing procedures of the final ESS-Bilbao RFQ, a 1 meter long RFQ Cold Model, including a longitudinal vane modulation, has been manufactured in aluminium. Low power RF measurements have been performed to obtain the main figures of merit of the cavity, including: frequency spectrum, coupling and quality factors, tuning range, RF sealing effect and the accelerating field profile. The experimental and simulated results are explained and analyzed.
