ADL5385ACPZ-R7 Présentation
A quadrature modulator is a key building block in modern wireless transmitters. It takes two baseband signals (I and Q) and modulates them onto a carrier signal, producing a modulated RF output. This architecture is fundamental to digital communication standards such as WCDMA, LTE, and WiMAX, where complex modulation schemes require precise I/Q balance. The ADL5385 simplifies the design of such transmitters by integrating the modulator function into a single IC, reducing component count and board space.
Key features of the ADL5385 include a wide operating frequency range from 30 MHz to 2200 MHz, excellent phase accuracy and amplitude balance, and a differential baseband interface. The device operates from a single 5V supply and provides a high output IP3, making it suitable for demanding linearity requirements. The LFCSP package with exposed pad ensures efficient thermal dissipation, while the tape and reel packaging (R7 suffix) is optimized for high-volume production.
Technically, the ADL5385 uses a double-balanced mixer topology with integrated quadrature phase splitting. This architecture provides high carrier feedthrough suppression and excellent sideband suppression, which are critical for spectral purity. The device also features a wide baseband bandwidth, allowing it to support both narrowband and wideband modulation schemes. Its performance is specified over the full -40°C to +85°C temperature range, ensuring reliable operation in diverse environments.
Typical applications include cellular base stations, point-to-point radios, satellite communications, and test and measurement equipment. In these systems, the ADL5385 is used to upconvert baseband I/Q signals to RF frequencies, enabling efficient and accurate signal transmission. Its high linearity and low noise make it ideal for high-performance communication links.
When designing with the ADL5385, it is important to provide proper decoupling on the supply pins and to match the differential baseband inputs to the driving source impedance. The exposed pad should be soldered to a ground plane for optimal thermal and electrical performance. Additionally, the LO input should be driven with a clean, well-leveled signal to achieve the best carrier feedthrough performance.

Principaux différenciateurs
- Wide frequency range from 30 MHz to 2200 MHz (vs ADL5370ACPZ-R7)
- Excellent phase accuracy and amplitude balance (vs ADL5371ACPZ-R7)
- Single 5V supply operation (vs ADL5372ACPZ-R7)
Notes de conception
The ADL5385ACPZ-R7 operates from a single 5V supply. It is critical to provide adequate decoupling on the VCC pin, using a 100nF capacitor placed as close to the pin as possible, along with a 10uF bulk capacitor. This ensures stable operation and minimizes supply noise that could affect modulation accuracy.
The exposed pad on the LFCSP package must be soldered to a ground plane for optimal thermal and electrical performance. Use multiple vias under the pad to enhance heat dissipation. Ensure the ground plane is continuous beneath the device to minimize parasitic inductance.
Match the differential baseband input traces to the driving source impedance, typically 50 ohms. Keep the LO input traces short and well-shielded to prevent coupling into the baseband or RF paths. Use a clean, well-leveled LO signal to achieve the best carrier feedthrough suppression.
