ABSTRACT:
A transmission line coupler (115) for a transmitter output signal (123) generated by an RF signal amplifier (103) includes a through-path transmission line (201) and a coupled-path transmission line (202) electromagnetically coupled thereto by multiple serpentine-like portions (such as portions 641, 642, 643 and 644 in FIG. 6), which are disposed on opposite sides of the through-path transmission line (201) for enhancing coupling sensitivity and eliminating degradation in the amount of coupling due to variations in the transmission line plating registration. Offset portions (641, 643) on one side of the through-path transmission line (201) provide substantially the same amount of coupling as the offset portions (642, 643) on the other side of the through-path transmission line (201). The transmission line coupler (115) is embedded in the output match of the final amplifier (103) and includes complex impedances (212 and 210, 222) at each port of the coupled-path transmission line (202) for substantially eliminating undesired reflections. The coupled port of the coupled-path transmission line (202) is coupled by an inductor (211) to a hot-carrier diode (206) for enhancing the detection sensitivity thereof.
