SILICON TRANSISTORS

DESCRIPTION

The 2SC2148, 2SC2149 are economical microwave transistors

encapsulated into new hermetic stripline packages, "micro X".

These are designed for small signal amplifier, low noise amplifier,

and oscillator applications in the L to C band, and CML circuit use.

FEATURES

2SC2148 NF: 2.1 dB TYP. @f = 500 MHz

2SC2149 NF: 2.6 dB TYP. @f = 2.0 GHz

Derating curves of the 2SC2148, 2SC2149.

The maximum junction temperature of these transistors is allowed up to 200

°C, but the ambient or storage

temperature is limitted to 150

thermal resistance mentioned on these derating curves.
