High-Frequency NPN Transistor Array For Low-Power Applications at Frequencies Up to 1.5GHz

The CA3227 consists of five general purpose silicon NPN transistors on a common monolithic substrate. Each of the transistors exhibits a value of fTin excess of 3GHz, making them useful from DC to 1.5GHz. The monolithic construction of these devices provides close electrical and thermal
matching of the five transistors.
