ULTA-10 | 0.25-220MHz Ultra Linear Laboratory Amplifier

ULTA-10 is a professional 10W ultra linear class-A broadband amplifier built on latest LDMOS technology, with high gain and wide frequency response, for laboratory grade tests and measurements, with outstanding linear performance such as low harmonics distortion and IMD products. It can be used to measure and describe intermodulation distortion products or harmonics behaviour for medium to high power HF to VHF linear amplifiers (for 500…600w: ULTA-10R3-1, for 800…1500W: ULTA-10R3-2) . Optimised for signal purity not for power consumption, it was designed and built especially to characterise IMD products for SSPA in HF-VHF, where ultra low distortion is needed. Built in a compact rugged case, externally supplied, with enhanced forced-air cooling. Operation over the band is achieved without any band switching or additional filtering. Compatible with most signal generators, frequency synthesisers, sweep generators or other laboratory signal sources. Accurately reproduces waveforms within its power and frequency ranges: AM, FM, CW, SSB etc.
