The ADRF6780 and ADRF6880 enable simpler system architecture, especially for customers seeking to cover multiple bands from 6 to 24 GHz, by replacing narrow-band devices, using fewer components, offering higher system reliability, and using less board space.
The reference platform combines baseband processing with RF circuitry to realize a digital microwave radio that enables a wide variety of applications covering 6 to 24 GHz. The initial system demonstrates an ADI agile RF transceiver in image rejection mode to up-convert the transceiver output to 6 to 9 GHz, while an FPGA board generates digital I/Q and waveforms.
These SiGe up/down converters and transceivers will be demonstrated at IMS2016, along with:
- A new wideband (1.8 to 2.7 GHz) Software Defined Radio (SDR) microcell featuring an envelope tracking RF power amplifier. The digital radio demonstrates the AD9361 RF transceiver with a 7 W, wideband GaN on SiC RF power amplifier. High linearity and efficiency is achieved through the use of envelope tracking (ET), while signal generation and control of the ET modulator are handled by the field-programmable gate array FPGA.
- A 5 W Doherty small cell 700 MHz evaluation board featuring wideband LDMOS ICs from NXP and universal duplexers from CTS.
