Additional Details

The 2SC4726 is characterized by its low noise figure, which is typically around 1.0 dB at 1 GHz. This makes it an excellent choice for use in low noise amplifier circuits. The transistor also features a high transition frequency (fT) of approximately 9 GHz, enabling it to provide good gain at high frequencies. The device is housed in a small surface mount package, which helps to minimize board space and simplify assembly. The transistor is designed to operate with a collector current of around 5 mA and a collector-emitter voltage of 5 V. It is important to use appropriate biasing techniques to ensure stable and optimal performance. The 2SC4726 is commonly used in VHF/UHF receivers, where it is used to amplify weak signals received from an antenna. It is also used in other RF applications where low noise and high gain are required.
