Transceivers aim at 25-33GHz and 37-43GHz for 5G NR research

  • Author:Ella Cai
  • Release on :2018-07-17
National Instruments is aiming at 5G NR research and prototyping with two series of millimeter wave (mmWave) radio heads that stretch coverage of its existing mmWave Transceiver System, across 24.5-33.4GHz and 37.0-43.5GHz.

“As the first phase of 5G NR wraps up and the 3GPP finishes defining the communications protocol, the standards body also has identified specific frequency bands intended for 5G,” said NI. “Various regulatory bodies across the globe have begun the process of allocating spectrum for mmWave 5G mobile access.”

The parts are:
24.5-33.4GHz
mmRH-3642 (Tx)
mmRH-3652 (Rx)
mmRH-3602 (Tx+Rx – pictured)
37-43.5GHz
mmRH-3643 (Tx)
mmRH-3653 (Rx)
mmRH-3603 (Tx+Rx)

Existing parts cover 71-76GHz.

All of the radio heads support 2GHz of bandwidth.

The heads contain attenuators and amplifiers for maximum gain control and noise figure, and can be connected to a user-provided antenna, such as a horn antenna or a phased array – Antenna connectors are different for each frequency band,

According to the firm: “While 28GHz leads in early deployments, 39GHz is another important frequency band that is being explored and is quickly gaining popularity.”
