E-band transceiver module targets carrier grade mobile backhaul
Filtronic has launched Morpheus II, its new generation of mmWave transceiver modules for E-band (71-76 GHz and 81-86 GHz) applications in carrier grade mobile backhaul.

Morpheus II is based on the company’s proven E-band transceiver platform, of which over 36,000 units have already been shipped and deployed worldwide. Each fully-integrated Morpheus II transceiver module contains all the transmit and receive functions necessary for the RF section of an E-band radio link, and provides a simple connection to a high data rate full-duplex modem. They are designed for easy incorporation into outdoor units, giving original equipment manufacturers (OEMs) the advantage of a rapid time-to-market while requiring minimal engineering resource.

Demand for E-band mmWave radio links is growing rapidly, as they can provide high capacity and high data rate XHaul for the latest 5G networks that are being rolled out globally. In 2018 E-band accounted for around 7% of wireless links,and is forecast to continue with year-on-year growth rates of around 36%, according to Dell’Oro Group.

Standard modules have a linear transmitter power control range of -4 dBm to +16 dBm, with an output third order intermodulation product (IP3) of typically up to +34 dBm at the top end of the range. An enhanced power option, extending the control range up to +25 dBm, is also available. With a low phase noise of ‑112 dBc/Hz at 1 MHz, the transceiver modules support a channel bandwidth in excess of 2 GHz. They have demonstrated system performance at data rates of 10 Gb/s with spectrally efficient 256QAM, and are capable of supporting even higher order modulation schemes. The internal low phase noise VCOs can be adjustedvia an SPI interface in 31.25 MHz steps,to support ECC/ITU channel arrangements.
