A K- band Transceiver for Wide Band Data Communication

()

Abstract:

A wide band T/R front-end at K-band for user terminal of tracking and data relay satellite system is introduced in this paper.The front-end uses coherent local oscillators that operate in multiple bands QPSK modulation and millimeter wave monolithic integrated circuits (MMIC) to perform transmitting and receiving data coherently with wide band,and provides directly digital interface at high bit rate for digital processing terminal.The front-end is compatible with several kinds of modulation patterns.In this paper,configuration and characteristics of the front-end,realization of major parts are also presented.Specifications of the T/R front-end satisfy the design requirments.
