Due to improper amplifier design, users of high-frequency components often encounter issues such as unwanted oscillations, poor ground shielding, nonlinearity, gain peaking, and reduced bandwidth. FEMTO high-frequency amplifiers have been designed to eliminate these undesirable problems. FEMTO high-frequency amplifiers are insensitive to signal source parameters and input wiring, performing accurately within their specifications. Even with source capacitances up to 2nF (for HCA-1M-1M-C), gain peaking, oscillations, or significant bandwidth reduction do not occur.
