DESCRIPTION
Dual transistor with two silicon NPN RF dies in a surface
mount 6-pin SOT363 (S-mini) package. The transistor is
primarily intended for wideband applications in the
GHz-range in the RF front end of analog and digital cellular
phones, cordless phones, radar detectors, pagers and
satellite TV-tuners.
