ADA-4643-BLKG

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.
