AD8099 High-speed op-amp

High-speed amplifier circuit based on AD8099

A high-speed amplifier circuit with 10x gain built using AD8099
has been verified. At 100MHz, it can amplify a 100mV peak-to-peak sine wave to approximately 900mV.
Single-sided routing is convenient for manual PCB fabrication.
Note: The SMA interface should be BWSMA-KE-PO01 (searchable on LCSC).

AD8099 chip introduction: Ultra-low distortion, high speed, 0.95NV/√Hz voltage noise operational amplifier; at a gain of 10, bandwidth up to 550MHz, slew rate up to 1350V/µs.
