Wlx-896b Schematic Today

The WLX-896B runs hot. If your schematic does not show thermal tracking resistors (e.g., a 100Ω PTC in the bias divider), add one. Otherwise, thermal runaway will destroy the finals. 3.5 Output Low-Pass Filter (7th Order) Typical values for 88-108 MHz (as seen on actual WLX-896B boards):

If you are repairing one, start with the power supply and bias voltages. Check the gate stopper resistors. And never trust the “stock” biasing – always set the idle current to 100mA per final device (monitor via the source resistors). The WLX-896B runs hot
