Hi all
I have a problem with my yaesu FTDX5000 radio. The main RX channel, RF AMP1 transistor, 2SC4536 SOT-89 was fault. The C-E was short.
I just searched digikey, mouser and any online shop, they were all stock-out, and 2SC4536 was also discontinued.
This transistor is not only a middle-power RF amplifier, but also has special features such as Low Distortion (low IM2 IM3) and large dynamic. Normal RF transistor may not have such features.
So does anyone know which one can replace 2SC4536? Thanks!
