As the GPS signal simulator is applied more and more extensively, the test equipment of the GPS signal simulator is required higher and higher. Currently, the calibration using the standard instrument is the most important means, which severely restricts the test environment of the simulator. In order to meet the test requirements of the GPS signal simulator for diversified situation, this paper proposes...
UHF RFID reader transceiver for Chinese local standard (840-845 MHz and 920-925 MHz), in concord with the protocols of EPC Class-1 Gen-2 and ISO/IEC 18000-6C, is presented. A highly linear RF front-end with low flicker noise, an on-chip self-jammer cancellation (SC) circuit with fast time-varying cut-off frequency and a DC-offset cancellation (DCOC) circuit are proposed to deal with the large self-jammer...
