Output coupler for preset position of HF output signal, using directional coupler |
摘要 |
The directional coupler (DIR) is fitted between output of a circuit (PA) and interface of a transmission channel, such as an aerial (ANT). The coupler insulated gate (3) is terminated by a resistance. The resistance magnitude is basically determined by an output resistance (ZPA) of the circuit and a reference (ZO) of the directional coupler, as per specified equation. The terminal resistance may be complex. A power component of given length may be included for resistance transformation. Independent claims are included for transceiver mobile radio range.
