    摘要： The present disclosure provides a preparation method of a metal powder material. An alloy sheet composed of a matrix phase and a dispersive phase with different chemical reactivities is prepared by the rapid solidification technique of alloy melt. Metal powder is prepared by the reaction of the alloy sheet and an acid solution. Please refer to the description for the detailed preparation method. This method is simple in operation, can be used to prepare many kinds of metal powder materials of different shapes and at the nanometer scale, the submicron scale and the micron scale, and has a good application prospect in the fields of catalysis, powder metallurgy and 3D printing.

    摘要： A transceiver for multi-standard operation (usable, for example, to communicate signals both of a first wireless communication standard and of a second wireless communication standard) has a mixer that receives a local oscillator signal generated by a local oscillator. A PLL of the local oscillator involves a VCO, a digitally programmable analog loop filter, a digitally programmable VCO supply voltage circuit, and a digitally programmable VCO varactor bias control circuit. In one aspect, the bandwidth of the analog loop filter is adjusted depending on the communication standard of the signal being communicated. In other aspects, the VCO supply voltage circuit and/or the varactor bias control circuit are configured in different ways to optimize PLL performance depending on the communication standard of the signal being communicated.

    摘要： Although the duplexer in a full-duplex transceiver circuit may only be guaranteed by the duplexer manufacturer to have a transmit band rejection from its TX port to its RX port of a certain amount, and may only be guaranteed to have a receive band rejection of another amount, the actual transmit band rejection and the actual receive band rejection of a particular instance of the duplexer may be better than specified. Rather than consuming excess power in the receiver and/or transmitter in order to meet performance requirements assuming the duplexer only performs as well as specified, the duplexer's in-circuit performance is measured as part of a transmitter-to-receiver isolation determination. Transmitter and/or receiver power settings are reduced where possible to take advantage of the measured better-than-specified in-circuit duplexer performance, while still meeting transceiver performance requirements. Power settings are not changed during normal transmit and receive mode operation.
