GENERAL DESCRIPTION
The 1617-35 is a high power COMMON BASE bipolar transistor. It is
designed for pulsed systems in the frequency band 1540 1660 MHz. The
transistor includes input and output prematch for broadband performance. The
device has gold thin-film metallization and diffused ballasting for proven
highest MTTF. Low thermal resistance Solder Sealed Package reduces junction
temperature, extends life.
