This compact RF front end meets the needs of multi-band, multimode transmit and receive requirements in software-defined-radio (SDR) picocell stations.
By optimizing a microstrip filters coupling structure, it is possible to achieve small size and wide rejection bandwidth while accounting for fabrication tolerances.
This high-performance receiver works with multiple active antenna modules and a digital intermediate-frequency (IF) stage to support wireless multicarrier and diversity receiving systems.
The amplitude response of a broadband RF transmit amplifier can be dramatically flattened by using the complementary characteristic of a bandpass filter.
This compact module is based on commercial ICs and standard PCB substrate, with the clever placement of filters to suppress unwanted transmitter spurious products.
