System Design of a High-Temperature Downhole Transceiver: Part I – Receiver

The paper presents a system level design of a receiver for high-temperature downhole communications. The receiver achieves required specifications necessary to have flexibility between power consumption and performance. The budget analysis considering the minimum system specifications for downhole communication is done. The simulations are performed in AWR design environment software. The simulation results show that the receiver can support a data rate up to 68 Mbps at 250 °C using Quadrature Phase Shift Keying (QPSK) modulation. Detailed simulation results and temperature effects on receiver specifications are included to prove its superior and reliable performance at high temperature using the 2.4 GHz – 2.5 GHz ISM band for the transceiver.
