Dalia Sadek, Heba A. Shawkey, Abdelhalim Zekry . Constructing Complete Radio Frequency Receiver for LTE TDD Transceiver. Communications on Applied Electronics. 3, 2 ( October 2015), 27-33. DOI=10.5120/cae2015651882
In this paper, the design, implementation and testing of the Zero IF receiver for Long Term Evolution (LTE) band 36 extending from 1930MHz to 1990MHz for TDD mode of transmission. Comprising a passive part and active part. The passive part consists of a microstrip patch antenna and a Hairpin BPF filter which are fabricated with a total area of 43x36mm2 for the antenna and 38.6x32.16mm2 for the filter. The proposed devices are fabricated using FR-4 material substrate with dielectric constant of Ɛr=4.4, thickens h =1.6, and Loss tangent of 0.025. The active part includes Low noise amplifier, IQ demodulator and frequency synthesizer. Which are a real made component selected off-shelf to satisfy the standards for LTE receiver characteristics. The proposed RF front-end receiver achieves a 4.022 dB NF, 2.65 dBm IIP3.
