DESCRIPTION N-P-N silicon planar epitaxial
transistor primarily intended for use in mobile transmitters in the 470 MHz band. FEATURES multi-base structure and emitter-ballasting resistors for an optimum temperature profile. gold metallization ensures excellent reliability. the device can be applied at a PL of max. 1,5 W when it is mounted on a printed wiring board (see Fig.6) without an external heatsink. The
transistor has a 4-lead envelope with a ceramic cap (SOT-122D). All leads are isolated from the mounting base. QUICK REFERENCE DATA R.F. performance in a common-emitter class-B circuit. MODE OF OPERATION narrow band; c.w. T °C Tmb = 25 Ta = Note 1. Device mounted on a printed wiring board (see Fig.6). PIN CONFIGURATION 25(1) VCE V 12,5 12,5 f MHz 470 470 PL W 2,5 1,5 Gp dB > 10 > 12
