The ADL5387ACPZ-R7 is a versatile RF demodulator and an integrated circuit (IC) from Analog Devices. This monolithic device is designed for a range of applications or subsystem functions, from communications and monitoring to radar and microwave engineering. It enables direct conversion of an RF signal to baseband, allowing signal processing systems to measure, detect, and decode wireless data.

The ADL5387ACPZ-R7 is comprised of a single-ended gain stage incorporating a common-source amplifier, a direct conversion receiver, and a demodulator. An active start-up circuit facilitates low standby current consumption while also providing enhanced first-stage linearity. This device features a 1-V noise figure, a wide frequency range from 0.2 to 10 GHz, and an input power range of -30 to 0 dBm. A variable gain control sets the required output level; a two-times gain selection is also implemented to further enhance the performance.

In terms of working principle, the ADL5387ACPZ-R7 works by converting the radio frequency (RF) signal to a lower frequency, typically baseband. The RF signal is first amplified and then downconverted to a lower frequency. This downconverted signal is then demodulated, eliminating any unwanted information, and a signal containing the desired data is produced.

The ADL5387ACPZ-R7 is ideal for a variety of applications, including base stations, radio modems, RFID readers, and point-to-point and point-to-multipoint radio links. It is suitable for operating at mmWave frequencies in communication systems for mobile and wireless applications. It can also be used in communication, instrumentation, digital radio broadcast, satellite TV, and broadcast devices.

The ADL5387ACPZ-R7 is a high-performance RF demodulator with a single-ended gain stage. It offers low standby current consumption and an improved linearity. The device also features a wide frequency range, a variable gain control, and a two-times gain selection, making it an ideal choice for a range of applications in communication, instrumentation, digital radio broadcast, and satellite TV.
