High frequency sensors for robust transmission in telemedicine system

This paper introduces a high frequency Point-to-Point (PtP) Microwave Transmitter Module for Telemedicine for hospital(s). Such a telemedicine system links up remote communities from one building to another in hospital environment. The network configurations of the high frequency microwave system are illustrated in details. Key advantages such as high capacity, long propagation distance, and wide range of frequency bands are described. The high frequency PtP serves as a repeater so that paramedical staff or nurse(s) may receive data at appropriate time. Hence important tasks such as first aid, doctor's diagnosis and instructions to patients may be performed through the telemedicine system. This paper describes the design of a telemedicine system based on a high linearity Ku-band transmitter module that can improve the capacity (data rate) as well as increased the propagation distance. The module operates between 13 ∼ 15.5 GHz and achieves 25 dB of gain and 33 dBm of output power at 1dB gain compression. The third order intermodulation (IM3) is -41 dBc at 22 dBm Pout/tone, when the two-tone space is 600KMz at the high centre frequency of 15GHz.
