ADL5372ACPZ-R7

The ADL5372ACPZ-R7 is a fixed-gain quadrature modulator from Analog Devices, operating within a frequency range of 1500 MHz to 2500 MHz. This device is engineered for high-performance intermediate frequency or direct radio frequency modulation in communication systems.

Key electrical specifications include a modulation bandwidth exceeding 500 MHz (3 dB), a 1 dB output compression of 14 dBm at 1900 MHz, and a noise floor of -158 dBm/Hz. It also offers sideband suppression of -45 dBc and carrier feedthrough of -45 dBm at 1900 MHz. The modulator requires a single supply voltage between 4.75 V and 5.25 V and consumes a typical current of 165 mA.

Fabricated using an advanced silicon-germanium bipolar process, the ADL5372ACPZ-R7 is available in a 24-lead LFCSP_VQ package with an exposed paddle. Its surface mount capability makes it suitable for various integration needs. The device is designed for applications such as cellular communication systems, CDMA2000/GSM/WCDMA, and WiMAX/broadband wireless access systems.

This modulator accepts two differential baseband inputs and a single-ended local oscillator (LO) input, generating a single-ended output. Its excellent phase accuracy and amplitude balance contribute to high-performance modulation, making it well-suited for broadband zero IF or low IF-to-RF applications and broadband digital predistortion transmitters.
