Others terminals may have a tool engaging shoulder configured to be engaged by a tool to force press-fit tails of all of the terminals into a circuit member. The housing may include a locking structure for certain the terminals that permits the terminals to be inserted into the housing with little or no force and then securely lock the terminals in the housing. One or more ground plates may be included for electrically connecting a plurality of the terminals.

Abstract: An electrical contact for insertion into a hole of a substrate. The electrical contact includes a compliant portion having an opening extending between contact arms. At least one contact arm of the contact arms has a resilient engagement section which extends into the opening of the compliant portion and resilient contacting sections which extend from the engagement section in a direction away from the opening. Upon insertion of the compliant portion into the hole of the substrate, the resilient engagement section of the at least one contact arm engages an opposed contact arm of the contact arms, causing each of the resilient contacting sections to move independently of the resilient engagement section and other resilient contacting sections. Each of the resilient engagement section and the resilient contacting sections are deformed and generate independent retention forces which are combined to generate the total retention force of the compliant portion.

Abstract: A connector removal tool comprising a rigid press and release device for removing a connector from an electronics assembly. Upon engagement of the rigid press and the release device, first and second press members of the rigid press engage and move about a pair of deflecting engagement members of the release device to cause the pair of deflecting engagement members to deflect to compress and unlock interlocking tabs of the connector to facilitate removal from the electronics assembly. A single motion of the rigid press can cause unlocking of the connector. Alternatively, a connector removal tool comprises biased deflecting rigid press members that engage directly with a connector to unlock the interlocking tabs of the connector to facilitate removal of the connector from an electronics assembly.

Abstract: pHEMT-based circuits and methods of improving the linearity thereof. One example pHEMT circuit includes a pHEMT connected between an input terminal and a load and a non-linear resistance connected to the pHEMT.

Abstract: A high bandwidth Hall sensor includes a high bandwidth path and a low bandwidth path. The relatively high offset (from sensor offset) of the high bandwidth path is estimated using a relatively low offset generated by the low bandwidth path. The relatively high offset of the high bandwidth path is substantially reduced by combining the output of the high bandwidth path with the output of the low bandwidth path to generate a high bandwidth, low offset output. The offset can be further reduced by including transimpedance amplifiers in the high bandwidth sensors to optimize the frequency response of high bandwidth Hall sensor.
