Increased wireless throughput via an IF-filterless dual-conversion receiver
This technology is an IF-filterless dual-conversion receiver that offers a tuned RF interface for greater out-of-band linearities and sufficient rejection of spurious responses.
Unmet Need: RF technology to improve 5G compatibility
Conventional device architectures are unable to accommodate growing front-end circuitry without significantly reducing the device’s operating frequency range and the out-of-band linearity. Additional unmet capabilities include blocker tolerance, concurrent reception capabilities, and rejection of spurious errors. New RF technology is needed to meet these design challenges and make more devices 5G-compatible without sacrificing key performance metrics.
The Technology: Blocker-tolerant, IF-filterless dual-conversion receiver for inter-band carrier aggregation
This technology is an IF-filterless dual-conversion receiver. It reduces device size by offering a tuned RF interface without needing hybrid couplers and filter banks. The technology introduces two direct digital synthesis modulated LNTA branches and four dual-conversion mixer-first branches for better noise cancellation and signal sensitivity. It efficiently combines low-noise design and direct digital synthesis modulation, enabling dual-carrier reception and offering sufficient rejection of spurious responses. This technology demonstrates high out-of-band linearity and has the potential to greatly increase the efficiency of carrier aggregations in RF devices, allowing it to potentially improve 5G compatibility.
