The existing 500 watt amplifiers are over 25 years old and it's output has dropped. The new amplifier will have a wider frequency range, so it will save us moving another amplifier from different calibration area to do measurements from 100 to 250 MHz. Reflective low pass filters will be used on the output of the amplifiers to reduce harmonics to acceptable levels. The proposed amplifier must be able to operate continuously at the rated output power when any harmonics generated are reflected back into the amplifier. Additional information: The Authority is using the LUPC Bravo e-Procurement portal to conduct the procurement process. All Suppliers must register their company via the LUPC Bravo Portal. ## CPV classification Laboratory, optical and precision equipments (excl. glasses) Source Contracts Finder (UK) [View official notice](https://www.contractsfinder.service.gov.uk/notice/05479357-4573-4a74-8e33-694b88fcdb59) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
