Richardson RFPD Inc. announced its participation in the 2016 IEEE International Microwave Symposium (IMS), to be held in San Francisco, Calif. May 24-26, 2016.

Richardson RFPD has collaborated with Analog Devices (ADI) and New Edge Signal Solutions to develop digital front-end (DFE) radio solutions, including new wideband (6-24 GHz) SiGe up/down converters (ADRF6780, ADRF6880) and transceivers. 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 6-24 GHz. The initial system demonstrates an ADI agile RF transceiver in image rejection mode to up-convert the transceiver output to 6-9 GHz, while an FPGA board generates digital I/Q and waveforms.

These new SiGe up/down converters and transceivers will be demonstrated at the Richardson RFPD booth (#1918) at IMS2016, along with:

• New wideband (1.8-2.7 GHz) Software Defined Radio (SDR)/microcell featuring envelope tracking RF power amplifier. The digital radio solution demonstrates the AD9361 RF transceiver with a 7W, 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.
• 5W Doherty small cell 700 MHz evaluation board. On display will be a 5W Doherty small cell 700 MHz board featuring wideband LDMOS ICs from NXP and universal duplexers from CTS.
