Abstract: A transformer (111) and its body (100) are made by molding a unitary transformer body with slots (101) that define a transformer core (102), and then cleaving the unitary body into a pair of "E"-shaped structures (104, 105) to facilitate mounting of transformer windings (110) in the slots around the core. Cleaving of the unitary body results in surfaces (108, 109) of the structures that abut each other being substantially perfectly matched to each other. Hence, costly polishing of those surfaces to ensure a substantially perfect fit between them is eliminated. After the windings are mounted, the pair of structures are attached together to re-form the transformer body and form the transformer.

Abstract: A transformer (FIG. 1) optimized for surface-mount vacuum-pickup automated circuit assembly eliminates the expense of a transformer housing. The transformer has a ferrite body (100) that defines a pair of wells (208, 209) each opening onto an opposite face (108, 109) of the ferrite body. Transformer primary and secondary windings are wound in a coil (103) through slots (210, 211) around a transformer core (204) at the bottom of the wells. The windings do not protrude from the wells beyond the faces, resulting in flat faces. A first plurality of conductive vias (104-106), one pair for each winding, are completely embedded in the ferrite body and extend to both of the faces. Each pair of vias serves at one face to attach to the winding and at the other face to attach to solder pods of a PC board. The embedded vias also serve as EMI filters. A plate (107) covers the one face and provides a surface for vacuum pickup and for labeling of the transformer. The ferrite body (500) of a first transformer (FIG. 5) adapted for stacked mounting of transformers dispenses with the flat plate and further defines a second plurality of pairs of conductive vias (104-106). These vias are not connected to the first transformer's windings, but rather are positioned for connection to the winding-connected first pairs of vias of a second transformer that is positioned orthogonally to and mounted on the first transformer at the one of the faces.

Abstract: A passive cascaded low-pass and high-pass filter comprises a conductive ferrite block (100) for filtering out some and not others of the frequencies of a multi-frequency electrical signal, and a pair of electrical contacts (101) on the block for connecting the unfiltered signal to the block and connecting the filtered signal from the block. The filter characteristic depends upon the ferrite's stoichiometry, but is independent of the ferrite's geometry. Signal attenuation caused by the filter evenly across the whole frequency range can be varied by varying the stress between one or both contacts and the block, via various stress-inducing mechanisms (400, 500).

Abstract: A passive positive-gain equalizer comprises a ferrite (100, 300) electromagnetically coupled to a single conductor (111, 311) of a digital signal defined in the frequency domain by a plurality of frequencies. Although it has no external power source other than the digital signal, the equalizer amplifies some of the signal's frequencies. In one embodiment, the equalizer (100) comprises a "C"-shaped body portion (101) whose legs (103, 104) extend through holes in a PC board (110) to be spanned by an "I"-shaped body portion (102). A tunnel (106) formed thereby surrounds a stripline (111) and the PC board portion (112) which carries the stripline. In another embodiment, the equalizer (300) comprises an "E"-shaped body portion (301) whose legs (303-305) extend through holes in a PC board (310) to be spanned by an "I"-shaped body portion (302). A pair of tunnels (306, 307) is formed thereby, and the stripline (311, 511) loops through each of the tunnels one or more times. The equalizer is tunable over a range of frequencies by varying the length or the number of the tunnels, by varying the number of loops the stripline makes through the tunnels, or by varying the number of the equalizers (300, 311) that are cascaded in series on the stripline (1211). Performance is improved by coupling a ferrite choke (800) in series with the stripline (111, 311) at the final output of the digital signal from the equalizer.

Abstract: An all-optical-loop buffer (100) that restores the extinction ratio of the buffered signal such as an ATM cell. The buffer takes advantage of the cross-gain compression and wavelength shifting effected by semiconductor optical amplifiers (SOAs 118, 132). A received signal (λ 1 ) is coupled (104) to the buffer loop (101), amplified (110), and combined (114) with a low-energy unmodulated second signal (116) at a different wavelength (λ 2 ). The combined signal is amplified by an SOA (118) to modulate the second signal with an inverse of the modulation of the first signal. The received signal is extracted (128) from the SOA's output and attenuated (126). The modulated second signal is extracted (124) from the SOA's output, amplified (122), and combined (130) with the extracted received signal. The combined signal is amplified by another SOA (132) to modulate the received signal with an inverse of the modulation of the second signal, thereby enhancing the extinction ratio of the received signal. The enhanced signal is then extracted (134) from the combined signal to substantially reproduce the signal as originally received. This signal may again be sent through the buffer loop, and the process may be repeated for as often as the signal needs to be buffered.

Abstract: An inductor (100) optimized for surface-mount vacuum-pickup automated circuit assembly eliminates the expense of an inductor housing. The inductor has a hollow rectangular ferrite core (101) and a winding defined by a stripline (102) deposited on the core surface. Winding ends are formed by conductive vias (103) in the core that open onto the core surface, where they connect and mount the inductor to a circuit board (150). A flat sheet (104) adhered to one face of the core provides a surface for vacuum pickup and for labeling of the inductor. The core of a passively tuneable inductor (200) defines multiple unconnected winding segments (102-103). Segment ends mount the inductor to the circuit board and connect the segments to circuit board striplines (254) that are laid out in a pattern to interconnect a number of the segments into a winding. The inductor is tuned by changing the stripline layout and thereby varying the number of interconnected segments. The core of an electromagnetic interference choke (300) defines two windings wound axially in parallel and radially in opposite directions. The core of a choke (500) that permits stacked mounting defines additional conductive vias (503) for connecting the windings of a second choke (300) mounted on the core to the circuit board. For electromagnetic isolation, the windings of the two chokes are oriented orthogonally to each other.
