Abstract
Systems and methods are provided for a transponder with several capabilities that are not present in conventional transponders. For example, an exemplary transponder in accordance with an embodiment of the present disclosure can be configured for two-way trans ponding, waveform generation, receiving, and antenna S11 measurement. In an embodiment, a transponder in accordance with an embodiment of the present disclosure can support multiple operating modes simultaneously. For example, a transponder in accordance with an embodiment of the present disclosure can interleave transponding, direct digital receiver, and waveform generation modes according to an order of precedence.
Claims20
A transponder, comprising:
- an antenna port;
- a coupler coupled to the antenna port;
- an antenna diagnostic module coupled to the coupler;
- a first switch coupled to the coupler, wherein the first switch is configured to couple the coupler to a receive (RX) module or a transmit (TX) module;
- and
- a field-programmable gate array (FPGA) coupled to:
- a first analog to digital converter (ADC), wherein an input of the first ADC is coupled to the antenna diagnostic module,
- a second ADC, wherein an input of the second ADC is coupled to a second switch, and wherein the second switch is configured to couple the second ADC to the RX module or the antenna diagnostic module, and
- a digital to analog converter (DAC), wherein an output of the DAC is coupled to the TX module.
A transponder, comprising:
- an antenna port;
- a coupler coupled to the antenna port;
- an antenna diagnostic module coupled to the coupler;
- a first switch coupled to the coupler, wherein the first switch is configured to couple the coupler to a receive (RX) module or a transmit (TX) module;
- and
- a field-programmable gate array (FPGA) coupled to:
- a first analog to digital converter (ADC), wherein an input of the first ADC is coupled to the antenna diagnostic module,
- a second ADC, wherein an input of the second ADC is coupled to a second switch, and wherein the second switch is configured to couple the second ADC to the RX module or the antenna diagnostic module, and
- a digital to analog converter (DAC), wherein an output of the DAC is coupled to the TX module, wherein the FPGA is configured to send a first control signal to the first switch to change an operating mode of the transponder.
