A board mount type right angle coaxial connector has a cylindrical body and a main body containing a dielectric and an air dielectric, respectively. The bodies are connected to each other at a right angle. The coaxial connector further has a conductor surrounded with the dielectric and the air dielectric. The conductor has also a right-angle structure and is protruded from a front side of the main body. An inner wall of the main body has a decreasing width and the conductor has a decreasing diameter. The coaxial connector may further has a fixing member for preventing pin rotation, a impedance matching ring, and ground supporters for mounting on the board.

The present invention relates to a connection structure in which an inner conductor is combined with a detachable impedance compensator as well as a coaxial connector, an extendible pin and an impedance compensator used for the connection structure. Further, this invention relates to a microwave device connected both electrically and mechanically with the connection structure. An impedance compensation thereof means compensates electric discontinuities between the inner conductor and the extendible pin by mechanical arraying with a microwave device to be combined with the connection structure, whereby the protrusion formed at the impedance compensation means satisfies the conditions, b≦a/5 and c≦2b, when diameter of the impedance compensation means is a, thickness thereof is b, and size of the protrusion is c.

A pressure conductive sheet includes a connector body formed of a thin plate of insulation material, an elastic body deposited as one body with the connector body, pluralities of connection terminals provided with a given interval to pass through the elastic body and the connector body, and a ground plate constituting a matching circuit, the ground plate being buried by a given width in between the connector body and the elastic body. The ground plate is coupled to a ground terminal among the connection terminals and is separated from an outer circumference face of a signal terminal. The connector body, the elastic body, the connection terminals and the ground plate are combined with one another to substantially reduce an interference between signal terminals through the matching circuit formed based on capacitance of a gap between a ground face of the ground plate and the signal terminal, and to improve electrical characteristics.

A vertical bonding wire inductor having a high quality (Q) factor and tunability, which can be manufactured using an existing wire bonding technology which is widely used for packaging integrated circuits, without an additional mask manufacturing process. The vertical bonding wire inductor includes at least one pair of bonding pads (3) occupying a predetermined area on a substrate (9) and one or more bonding wires (1) for connecting one or more pairs of bonding pads (3). The bonding wire (1) has a loop shape having a predetermined height. Due to the improved electrical characteristics, stability in process, tunability without an additional mask manufacturing process, and relatively low manufacturing cost, the vertical bonding wire inductor can be useful in production of economical microwaves devices.
