A microwave frequency device includes: a first substrate having a dielectric layer and a conductive film disposed on opposing first and second sides of the dielectric layer, the conductive film on the first side of the dielectric layer of the first substrate including at least one signal line; and a second substrate having a dielectric layer, conductive film disposed on at least one of first and second opposing sides of the dielectric layer, and at least one cut-out where the dielectric layer and conductive film have been removed, wherein the first and second substrates are bonded together to form a bonded assembly such that (i) a portion of the signal line of the first substrate is sandwiched between the dielectric layers of the first and second substrates, and (ii) the at least one cut-out exposes a portion of the signal line, thereby forming a microstrip portion. A method of forming same is also disclosed.

An improved modulator circuit for mixing a modulation signal with a carrier signal includes first and second harmonic mixers which are operative to produce modulated output signals at an output frequency corresponding to both the sum and the difference of the modulation signal frequency and the even harmonic frequencies of the carrier signal frequency. In one configuration employing a 90. degree. hybrid, the output signals of the harmonic mixers are combined to produce a single sideband modulated output signal. A novel harmonic mixer circuit is also provided along with demodulator circuits and methods of modulating and demodulating modulation signals.

A hermetically sealed surface mount electronic component package can be manufactured by converting standard, readily available flat-packs. The package has a base, with an opening through which a primary transmission lead extends, a glass-to-metal seal surrounding the transmission lead in the opening, and a secondary transmission lead extends from the primary transmission lead so that it is spaced from the base and its end is at least flush with the bottom of the base. An insulator can be provided between the primary transmission lead and the secondary transmission lead. A method of converting a standard flat-pack by providing a composite piece having a dielectric insulator, a secondary transmission lead for connection to the transmission lead of the flat-pack, and a connecting member for connecting the insulator and secondary transmission lead to the base of the flat-pack is also described.

A surface mount package particularly suitable for transformers and other components having numerous windings of fragile, difficult to handle wire has a housing which includes openings along the lower edge, the housing being plated with an electrically conductive material on portions of the lower edge and in areas surrounding the opening. A component is held within the housing, and the leads of the component are disposed in the openings at a point above the lower edge of the housing, and the leads are electrically connected to the plating surrounding the openings and the plating at the flat portions of the lower edge. The plating on the flat portions of the lower edge can be at any suitable location, i. e. , remote from or adjacent to the openings. Additional components can be stacked on the exterior of the housing, as connected to the plating surrounding the openings.
