Analog Devices Inc. ADL5386ACPZ-R7

Overview

ADL5386ACPZ-R7 from Analog Devices is a 50 MHz to 2200 MHz quadrature modulator with integrated logarithmic detector and voltage-variable attenuator (VVA), designed for RF transmitter signal chains in broadband wireless infrastructure. It delivers 5.5 dBm typical SSB output power at 350 MHz, −46 dBc sideband suppression, and 30 dB linear AGC dynamic range, enabling high-data-rate modulation in cable modem termination systems and cellular base stations.

For engineers reviewing the ADL5386ACPZ-R7 datasheet, ADL5386ACPZ-R7 pinout, ADL5386ACPZ-R7 application, or ADL5386ACPZ-R7 equivalent, this page provides verified specifications, functional pin mapping, real-world use cases in WiMAX and microwave radio links, and validated alternative parts for RF transceiver design and AGC loop implementation.

Technical Context

The ADL5386ACPZ-R7 implements a SiGe/GaAs hybrid architecture: one die handles IQ modulation and bias generation, while the other integrates the VVA and log detector. Its quadrature phase splitter derives orthogonal carriers from a single-ended LO input at twice the output frequency, supporting direct RF and low-IF modulation topologies.

It features three co-integrated functional blocks: a wideband (700 MHz) differential baseband-input modulator, a standalone logarithmic detector with ±1 dB dynamic range up to 28 dB (at 50 MHz), and a reversible VVA with 37.8 dB attenuation range at 50 MHz-each with independent I/O pins and configurable open-loop or closed-loop AGC operation.

Key Specifications

Pinout & Package

ADL5386ACPZ-R7 is housed in a 40-lead, Pb-free LFCSP_VQ package (6 mm × 6 mm, 0.85 mm height) with an exposed thermal paddle that must be soldered to a low-impedance ground plane per Analog Devices' layout guidelines.

FAQ

What is the operating frequency range of the ADL5386ACPZ-R7?

The ADL5386ACPZ-R7 operates from 50 MHz to 2200 MHz for RF output, with its external LO input required at twice that frequency (100–4400 MHz). This range covers UHF, L-band, S-band, and lower PCS/UMTS bands, supporting applications including microwave radio links and cable modem termination systems. Performance metrics such as sideband suppression and output P1dB are specified across this full span.

Does the ADL5386ACPZ-R7 support both open-loop and closed-loop AGC modes?

Yes, the ADL5386ACPZ-R7 supports both modes. In closed-loop AGC, the integrated logarithmic detector compares RF output power against a setpoint applied to VSET and drives the VVA via VDET/VCTL. In open-loop mode, an external voltage (0–2 V) is applied directly to VDET/VCTL to control VVA attenuation, with the detector disabled by tying TADJ to VPOS. Both configurations are validated in the datasheet.

What is the purpose of the TADJ pin on the ADL5386ACPZ-R7?

The TADJ pin on the ADL5386ACPZ-R7 serves two functions: (1) temperature compensation for the on-chip log detector's AGC loop, configured with a 22.1 kΩ resistor to ground; and (2) detector enable/disable control-connecting TADJ to VPOS disables the detector section, which is required when operating the VVA in open-loop mode. This dual role ensures stable AGC performance across −40°C to +85°C.

Can the ADL5386ACPZ-R7 be used without the integrated VVA?

Yes, the ADL5386ACPZ-R7 can be used with the VVA bypassed. The modulator output (MODOUT) may be routed directly to external circuitry, and the VVA section can be disabled by leaving ATTI/ATTO unconnected and setting TADJ to VPOS to disable the detector. The quadrature modulator remains fully functional, delivering SSB RF output with −46 dBc sideband suppression at 350 MHz and supporting baseband or low-IF drive architectures.

What package type and thermal characteristics does the ADL5386ACPZ-R7 have?

The ADL5386ACPZ-R7 uses a 40-lead Pb-free LFCSP_VQ package (6 mm × 6 mm, 0.85 mm height) with an exposed thermal paddle. When soldered to a low-impedance ground plane, it achieves a junction-to-ambient thermal resistance (θ_JA) of 38°C/W. This allows sustained operation at 245 mA supply current and +85°C ambient temperature, making it suitable for thermally demanding RF transmitter modules in outdoor infrastructure equipment.
