Product Description
The NBT-168 discrete HBT is ideal for low-cost amplifier
and oscillator applications up to 12GHz. Low noise figure,
high gain, high current capability, and medium output give
this device high dynamic range and excellent linearity for
cascaded amplifier designs. This device is also ideally
suited for VCO/buffer amplifier applications. The NBT-168
is packaged in a low-cost, surface-mount ceramic pack-
age, providing ease of assembly for high-volume tape-
and-reel requirements. It is available in either packaged
or chip (NBT-168-D) form, where its gold metallization is
ideal for hybrid circuit designs.
