摘要： PROBLEM TO BE SOLVED: To prevent a faulty electrical contact between an electrical circuit connection part of an antenna and an antenna connection part of an electrical circuit by holding a lump-shaped elastic conductor material between the electrical circuit connection part and antenna connection part and fixing the conductor material by compressing it. SOLUTION: A lump-shaped elastic material 10 is held between an electrical circuit connection part 9 of an antenna and an antenna connection part 7 of an electrical circuit. Then the material 10 is compressed in a flat shape and fixed in a casing 1, to secure conduction between both parts 9 and 7. Then the part 7 is located on the same substrate 2 as the electrical circuit and also on a shielding member 3 which covers the electrical circuit. The contact area is increased by compression between both parts 7 and 9. Furthermore, the part 7 has a recess/projection, so that a part of the material 10 enters in or cut in.

摘要： A radio terminal device comprises an antenna (10), a transmitter circuit (11), a direct conversion receiver circuit (12), a circulator (13), and a band-rejection filter (14). A direct conversion receiver circuit (12) is smaller in size than a heterodyne receiver circuit and involves fewer spurious signals to be removed. Therefore, the entire radio terminal device becomes small. In addition, the direct conversion receiver circuit (12) comprises even-harmonic mixers (20, 21), and the frequency (flo) of a local oscillator (LO) is 1/2 of the received signal frequency (frx), so that there is no deterioration in sensitivity due to the leakage of local oscillation wave (LO) to the antenna (10).

摘要： In a cellular telephone having a receiving circuit (14) of a direct conversion type using an even harmonic orthogonal mixer (24), high-pass filters (56, 58, 64, 66) for removing a DC offset component are arranged before and after a variable gain amplifier (60, 62) in a base band circuit (30). The DC offset component occurred in the even harmonic orthogonal mixer (24) is always constant, and the DC offset component occurred in the variable gain amplifier (60, 62) frequently varies so that a cutoff frequency (fc1) of the front high-pass filter (56, 58) is set to be lower than a cutoff frequency of the rear high-pass filter (64, 66), and the frequencies are set to achieve a fast transition response.
