Pad die transmission circuit coupler null for Radio Frequency signal amplifier

摘要

(57) Abstract The transmitter output signal which generates the RF signal amplifier (103) by (123) as for the transmission circuit coupler of business, the direct communication path transmission circuit (201) with, the multiple snake condition parts (electromagnetism is joined the join path transmission circuit which (202) with to include in the direct communication path transmission circuit the part 641,642,643,644 and the like in the 6th figure) due to, these snake condition parts the direct communication path transmission circuit (201) to be laid out on hostility side, to improve join sensitivity, expulsion the degradation of the join tonnage at the same time with the gap of transmission circuit plated registration. The direct communication path transmission circuit (201) one side the offset part with respect to side (641,643), the direct communication path transmission circuit (201) the offset part with respect to other side (642,643) with it possesses the same join tonnage substantially. Expulsion the reflection where the transmission circuit coupler (115), the last amplifier (103) it is padded by output matching, complex impedance (212 and 210,222) it includes in addition the join path transmission circuit (202) in each port, is not desirable substantially. The join path transmission circuit (202) the join port the hot carrier diode (206) is joined the inductor (211) by, improves the detection sensitivity.
