РЧ-усилитель ADA-4643-BLKG

РЧ усилитель , 17.5дБ усиление / 4дБ шум, DC до 2.5ГГц, 3.2В до 3.9В питание, SOT-343-4

The ADA-4643-BLKG is a silicon Bipolar Darlington Amplifier provides inherent broad bandwidth performance and resulting in useful operating frequency up to 2.5GHz. This is an ideal device for small-signal gain cascades or IF amplification. The amplifier is fabricated using Agilent's HP25 silicon bipolar process, which employs a double-diffused single polysilicon process with self-aligned submicron emitter geometry. The process utilizes industry standard device oxide isolation technologies and submicron aluminium multilayer interconnects to achieve superior performance, high uniformity and proven reliability.

• Small signal gain amplifier
• Unconditionally stable
• 50R Input and output
• Up to 1GHz response
• Economical and easy to use
• 20 to 60mA Operating current range
