ALS AIP RF Amplifier Replacement

LBNL plans to procure two (2) units of 25 kW (peak) pulsed RF solid-state (LDMOS/GaN-based) High Power Amplifiers (HPAs):

• One (1) unit operating at approximately 125 MHz
• One (1) unit operating at approximately 500 MHz

These new HPAs will replace the existing tube-based ALS Sub-Harmonic Buncher (SHB) pulsed RF amplifier systems. LBNL believes this opportunity may be of interest to bidders with relevant experience in this field.

Bidders are kindly requested to complete the attached SHB Pulsed RF HPA High-Level Specification Requirements (dated 12 Oct 2025) Excel sheet by filling in Columns D and E with their responses. In addition, please provide:

• Relevant technical documentation and drawings (if available)
• Examples of similar HPAs currently in operation (particularly in accelerator laboratories or comparable environments)
• An estimated budgetary quotation for two (2) HPA units
• An estimated delivery schedule

Bidders are also encouraged to include any additional technical insights, design features, or value engineering considerations that highlight the strengths and uniqueness of their pulsed RF HPA solutions.
