RUA Block Diagram

RDA Block Diagram

RUDA (RF Up-Down Converter Assembly) transforms an analog signal of intermediate frequency bandwidth to carrier wave and carrier wave to analog signal of intermediate frequency bandwidth from HSDPA LCR TDD Node-B (HTR-NB20) system.

UDA consists of two parts: RDA (RF Down-Converter Assembly) to transform carrier wave signal received from FEU of HSDPA to an analog signal of IF bandwidth and transmit it to DUDA and RUA (RF Up-Converter Assembly) to receive an analog signal of IF bandwidth from DUDA and transmit carrier wave signal to HPA(High Power Amplifier).
