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.
