A method and system for determining position and/or pose of an object. A robotic device moves throughout an environment and includes a master transceiver tag and, optionally, additional tags. The environment includes a plurality of anchor nodes that are configured to form a network. A master anchor node is in communication with at least a portion of the plurality of anchor nodes and is configured to transmit a ranging message as a UWB signal, receive a ranging message response from each other anchor node in the network, generate a reference grid representing physical locations of the plurality of anchor nodes within the network based upon the received ranging message responses, and distribute the reference grid to each of the other anchor nodes. The master transceiver tag receives the reference grid information and, based upon further calculations, determines a specific position and pose of the robotic device within the environment.

An RF receiver includes a low-noise amplifier (LNA) to receive and amplify RF signals, a transformer-based IQ generator circuit, one or more load resisters, one or more mixer circuit, and a downconverter. The transformer-based IQ generator is to generate a differential in-phase local oscillator (LOI) signal and a differential quadrature (LOQ) signal based on a local oscillator (LO) signal received from an LO. The load resisters are coupled to an output of the transformer-based IQ generator. Each of the load resisters is to couple one of the differential LOI and LOQ signals to a predetermined bias voltage. The mixers are coupled to the LNA and the transformer-based IQ generator to receive and mix the RF signals amplified by the LNA with the differential LOI and LOQ signals to generate an in-phase RF (RFI) signal and a quadrature RF (RFQ) signal. The downconverter is to down convert the RFI signal and the RFQ signal into IF signals.

In some applications network parameters vary over time in a manner that precludes the use of conventional swept frequency network analyzers. Swept measurements incur penalty both in terms of acquisition time, and in terms of registration between measurements taken at the beginning and at the end of a sweep. Disclosed is an architecture and method for real-time analysis of network parameters. Example applications are presented, ranging from thermal drift of amplifiers, to microwave imaging of moving objects, to characterizing materials on conveyors, to characterizing plasma buildup, and many more.

A radio-frequency (RF) apparatus includes a wideband receive (RX) impedance matching circuit to provide a received differential RF signal to RF receive circuitry. The wideband RX impedance matching circuit includes first and second inductors to receive the differential RF signal. The wideband RX impedance matching circuit further includes a third inductor coupled across an input o the RF receive circuitry. The third inductor performs the functionality of a capacitor having a negative capacitance value.

A Multi-Signal Instantaneous Frequency Measurement, MIFM, system comprising a front end adapted to shift and combine signal spectra of different sub-frequency bands (SFBs) of a received wideband signal (WBS) into an intermediate frequency band (IFB) having an instantaneous bandwidth (IBW), wherein each shifted SFB signal spectrum is marked individually with SFB marking information associated with the respective sub-frequency band (SFB) and a digital receiver (3) having the instantaneous bandwidth (IBW) configured to process the shifted SFB signal spectra within the intermediate frequency band (IFB) using the SFB marking information to resolve any frequency ambiguity caused by the shifting and combining of the SFBs signal spectra.

RF front end circuitry includes a first antenna node, a second antenna node, a diplexer, a first band filter, a second band filter, and switching circuitry. The diplexer may be used to separate signals for carrier aggregation, providing signals within a first RF frequency band to the first band filter and signals within a second RF frequency band to the second band filter. Further, by strategically arranging the switching circuitry, the diplexer may also be used as a multiple-input-multiple-output filter, such that additional filters are not required to support one or more MIMO modes of the RF front end circuitry.

A multi building block architecture may be configured to generate a waveform (a target wideband signal) for use in a wireless communication system, where the waveform supports a variety of baseband signals. The task of generating a target wideband signal can be divided into several tasks, each task relating to the generating of one of a plurality of sub-carrier bands. Each of the sub-carrier bands (sub-bands) may be generated by one of the sub-band building units included in the sub-band building blocks of the architecture. Several sub-bands may be formed, by a sub-band group building block, into a sub-band group. Multiple sub-band groups may be formed, by a wideband building block, into the target wideband signal.
