Users of high frequency components are often confronted with problems including unwanted oscillation, poor ground shielding, nonlinearities, gain peaking and bandwidth reduction caused by poorly designed amplifiers. FEMTO High Frequency Amplifiers have been designed to eliminate such unwanted problems. Insensitive to signal source parametres and input wiring, FEMTO High Frequency Amplifiers perform meticulously within their specifications. No gain peaking, oscillation or significant bandwidth reduction will occur, even for source capacitances up to maximum 2 nF (for the HCA-1M-1M-C). Amplifier models shown with an additional "C" are optimised for handling very large source capacitances up to nanofarads.

Applications include: Amplifier for fast detection with large area photodiodes, spectroscopy, photodiode amplifier, PMT amplifier, ionisation detectors, pyro and piezoelectric sensor
