  DC9018A-C is a radio frequency (RF) evaluation and development kit, board, specifically designed for application with the Qorvo GC4000 power amplifier (PA) module. It provides a comprehensive platform for quick and easy testing and evaluation of the PA performance. The kit is designed to enable rapid prototyping of new PA architectures and topologies, with the added capability to run multiple measurements. It is especially suitable for research, development and design engineers and technical personnel in various industries and academic institutions.

  The DC9018A-C consists of a carrier board and a daughter board. The carrier board provides the power supply for the board, a signal source, a reference signal, an adjustable bias voltage, and the connection to other RF measurement equipment. The daughter board consists of the Qorvo GC4000 power amplifier, an input terminal, an output terminal, an 8-bit audio D/A (digital-to-analog) converter, and an optional antenna connector.

  The working principle of the DC9018A-C is based on the application of signal sources, measuring and sampling electronics and control software. The RF signals generated from a reference source are routed into the GC4000 PA, and then measured at the output. The output signal parameters are compared to specifications. The bias voltage circuit adjusts the PA bias setting in order to achieve the desired intention. The 8-bit audio D/A converter supplies the signal being sent to the input of the PA module and can be configured for different waveforms and amplitude.

  The DC9018A-C evaluation and development kit, board enables engineers and technicians to measure gain, power, frequency response, impedance, harmonic distortion, modulation accuracy and interferences. It also provides the capability for frequency agility and reciprocal measurements between the input and output signal. Additional features of the kit include automated testing for evaluating power amplifier gain versus temperature, power amplifier stability versus temperature and the ability to monitor the power gain of the PA stages over time or a specific period.

  The DC9018A-C RF evaluation and development kit, board is a powerful instrument for improving the design of RF systems and components and for developing innovative solutions. Due to its versatility and multiple measuring functions, it is also an ideal choice for a range of other applications, including auditing and troubleshooting, allowing fast and accurate testing of RF systems.
