This document contains draft specifications for four solid-state radio frequency amplifiers required by the Naval Research Laboratory. The amplifiers must meet specified frequency ranges, output power, gain, input/output connector types, and distortion measures. Amplifier 1 is required for 2-18 GHz with a minimum 20W output and SMA connectors. Amplifier 2 also operates over 2-18 GHz but with a minimum 50W output and Type N connectors. Amplifier 3 is specified for 26.5-40 GHz with a minimum 10W output and 2.92mm connectors. Amplifier 4 in this range must provide a minimum 20W with 2.92mm input and WR28 flange output connectors. The associated federal contract opportunity posting indicates the Navy is seeking potential sources to meet these draft amplifier specifications.

N00173-24-RFI-NY06

Specifications The Naval Research Laboratory (NRL) has a requirement for solid-state radio frequency (RF) amplifiers for lab measurement of RF electronics.

A. The primary requirement is for solid-state RF amplifiers for use in performing lab measurements of RF solid-state device components and circuits. For longevity and reliability, the amplifiers must have integrated protection circuitry and pass typical ageing and burn-in testing. All amplifiers must come with at a 2 year warranty, have variable gain adjustment, be air-cooled, and have readable display presenting operation status to include self-check of critical components. All specifications below must be met across the entire specified frequency range. The amplifiers must be standard commercial products with demonstrated field use.
