The ADL5387ACPZ-WP is a demodulator in the RF demodulator family. It is a low power, wide bandwidth, linear component box that is ideal for data acquisition, monitoring, and signal-processing in the Amateur Radio market. This demodulator is designed to take a full-duplex dual-carrier baseband signal and process it with the accuracy and speed required to create a high-performing component. Additionally, it is engineered to operate with low current consumption and a low noise figure.

The ADL5387ACPZ-WP is an ideal solution for applications that require high linearity, low noise, and wide dynamic range in a small package. It is capable of serving as a carrier-processing engine for multiple types of telecommunication systems. This includes multiple data formats like Fixed-QAM, QAM/OFDM, and spread spectrum systems. Additionally, this RF demodulator is known for its extended temperature range and high linear gain while exhibiting a low noise figure and low DC power consumption across its full dynamic range.

The ADL5387ACPZ-WP demodulator has a three-stage architecture, which includes the RF stage, the IF stage, and the baseband stage. The RF stage boosts the signal level and removes any unwanted signals that are out of the desired antenna band. The IF stage further amplifies the signal and applies any filtering that is necessary to eliminate out-of-band noise. Finally, the baseband stage applies noise cancellation, performs demodulation, and provides low-level gain control prior to the output.

The baseband stage consists of a programmable gain amplifier, a quadrature demodulator, and a digital decoder. The first two components serve to recover the analog signal from the analog-to-digital converter. The decoder is responsible for converting the received data into digital data. Additionally, the demodulator adjusts the gain of the system to provide optimal performance, while the digital decoder processes the signal in order to create the desired output. The step-by-step processing of the received signal ensures that the output is of high quality.

The ADL5387ACPZ-WP is the perfect component for Amateur Radio and data acquisition applications that require both high linearity and robust performance. The three-stage architecture provides superb signal-to-noise ratio, high linear gain, and low-power operation. The programmable gain amplifier, quadrature demodulator, and digital decoder allow the demodulator to efficiently process even the most complex signals and achieve desired levels of performance.
