The construct configuration of buffer resistors are as per the IPSS-1-10-002-82 with amendment no. Free Next Day Delivery. The diode provides a DC voltage on C16 that increases with RF power, as in this plot. Oxygen Sensor Replacement E36. But most loads don't draw exactly the same current at all times, so this approach is rarely useful in practice.
