Product Description

The LPT16ED is a silicon germanium low phase
noise, high frequency NPN transistor for oscillator
applications up to 16GHz.

The transistor exhibits low 1/f noise and provides
+13 dBm typical output power at V
equal to 20 mA. It is easily operated from a single
supply voltage with appropriate external passive
components.

The silicon germanium technology used in this device
provides outstanding high-frequency performance
combined with high thermal conductivity and superior
reliability under harsh operating and storage
conditions.

A complete mechanical description of the transistor is
available under SiGe Semiconductor Document
07MS001.
