RCA-2N3478 is an epitrucial planar transistor of the silicon n-p-n 1;ype with characteristics which make it extremely useful as a general purpose rf amplifier at frequencies up to 470MHz. These characteristics include an exceptionally low noise figure at high frequencies, low leakage current, and a high gain-bandwi dth product. The 2N3478 utilizes a hermetically sealed fourlead package in which active elements of the transistor are insu...
