2.4GHz Directional Coupler
... For example a typical 2.4GHz NIC card might generate 100mW, or 2.23V into 50Ω. The forward coupler should then pick up 0.23V, and perhaps a dc output of 0.3V. A gain of 30 should produce full-range on the meter (9V, 50µA, 180kΩ). The reflected wave may be negligible if the line is matched to a good ...
