Renesas Electronics Corporation Bipolar RF Transistors 2SC4228-T1-A

The 2SC4228 is an NPN silicon RF transistor for high-frequency low-noise amplification in VHF and UHF applications, packaged in a 3-pin super minimold surface-mount format. It operates with a maximum collector-to-emitter voltage of 10 V and a collector current of 35 mA, dissipating up to 150 mW in free air. At VCE = 3 V and IC = 5 mA, it achieves a typical noise figure of 1.9 dB and insertion power gain of 7.5 dB at 2 GHz, with a gain-bandwidth product of 8.0 GHz. The device meets a junction temperature limit of 150 °C and is rated for storage from -65 °C to +150 °C.
