Product details
Overview
ADL5386ACPZ-R2 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-R2 datasheet, ADL5386ACPZ-R2 pinout, ADL5386ACPZ-R2 application, or ADL5386ACPZ-R2 equivalent, this page provides verified functional identity, validated 40-lead LFCSP_VQ package mapping, confirmed differential I/Q baseband interface, LO×2 architecture, and two rigorously cross-checked alternative modulators with documented performance trade-offs.
Technical Context
The ADL5386ACPZ-R2 implements a direct-conversion IQ modulator architecture using an external LO signal at twice the desired RF output frequency, with internal quadrature phase splitting and SiGe/GaAs dual-die integration. Its baseband inputs accept 1.4 Vp-p differential sine waves on 500 mV dc bias, supporting up to 700 MHz 3 dB bandwidth.
It integrates three functionally independent subsystems: a wideband IQ modulator with <±0.5° quadrature error at 350 MHz; 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 and 17 dB at 2150 MHz, controlled via VCTL pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Frequency Range | 50 MHz to 2200 MHz - supports full-band operation from low-VHF through PCS/UMTS/LTE bands without reconfiguration. |
| SSB Output Power @ 350 MHz | 4–7 dBm typ - sufficient to drive subsequent PA stages with headroom for linear amplification. |
| Sideband Suppression | −46 dBc unadjusted @ 350 MHz - reduces adjacent-channel interference in OFDM-based transmitters. |
| VVA Attenuation Range | 37.8 dB @ 50 MHz, 17 dB @ 2150 MHz - enables precise closed-loop AGC across multi-band systems. |
| Log Detector Dynamic Range | 28 dB ±1 dB @ 50 MHz - allows accurate RF power monitoring over four decades of input level. |
| Modulator Voltage Gain | −1.4 dB @ 350 MHz - provides predictable gain scaling for baseband DAC output matching. |
| Supply Voltage | 4.75 V to 5.5 V - compatible with standard 5 V supply rails and tolerant of industrial-grade ripple. |
| Operating Temperature | −40°C to +85°C - qualified for outdoor macrocell and remote radio head environments. |
Pinout & Package
ADL5386ACPZ-R2 uses a 40-lead, Pb-free LFCSP_VQ package with exposed paddle (EPAD), requiring low-impedance grounding per Analog Devices' thermal and EMI guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IBBP / IBBN / QBBP / QBBN | Differential I/Q baseband inputs | High-impedance, externally biased (500 mV dc) inputs accepting 1.4 Vp-p differential signals; no internal biasing. |
| LOIP / LOIN | Single-ended LO input (×2 frequency) | Accepts ac-coupled LO at twice RF output frequency; 50 Ω matched; −7 dBm typical drive level. |
| MODOUT | Single-ended RF modulator output | 50 Ω internally biased output; intended for direct connection to ATTI or ATTO of integrated VVA. |
| ATTI / ATTO | VVA RF input/output terminals | Reversible ports: ATTI typically receives MODOUT; ATTO drives next stage; both require ac-coupling. |
| VDET/VCTL | Detector output / VVA control voltage | In open-loop mode: 0–2 V analog control sets VVA attenuation; in AGC mode: open, driven by internal loop. |
| VSET | AGC setpoint or detector measurement reference | Defines target RF power level in closed-loop AGC; in standalone detector mode, shorted to VDET/VCTL. |
| ENBL | Modulator enable/disable control | Logic-high (≥1.5 V) enables full device; logic-low disables modulator, reducing current to 2.2 mA sleep mode. |
| TEMP | Integrated temperature sensor output | Analog voltage (1.45 V @ 27°C, −4.6 mV/°C slope) for system-level thermal compensation or monitoring. |
| TADJ | Temperature compensation & detector enable | 22.1 kΩ resistor to ground enables log amp temp compensation; tied to VPOS disables detector section. |
| COMM / VPOS / EPAD | Ground, supply, and thermal pad | 12 × VPOS pins ensure low-noise supply distribution; EPAD must be soldered to ground plane for θJA = 38°C/W. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated VVA with reversible I/O | Enables flexible placement in transmit chain-can precede or follow external filters/amplifiers without redesign. |
| Standalone logarithmic detector | Provides calibrated RF power measurement (−33 dBm to −10 dBm) independent of modulator/VVA operation. |
| 700 MHz baseband bandwidth | Supports direct drive from high-speed DACs or complex IF signals up to 350 MHz carrier without external upconversion. |
| Quadrature accuracy & amplitude balance | <±0.5° phase error and ≤0.05 dB I/Q amplitude imbalance at 350 MHz preserve EVM in 256-QAM systems. |
| Single 5 V supply operation | Eliminates need for dual-rail supplies or LDOs, simplifying power delivery in space-constrained RF modules. |

|
Use Scenario: Outdoor pico/femtocell operating in 1800/2100 MHz bands with MIMO 2×2 configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quadrature modulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADL5387ACPZ-R7 | Wider 30–2200 MHz RF range; higher 13 dBm P1dB; no integrated VVA; requires external detector. | Better suited for wideband test equipment or multi-standard radios where VVA flexibility is secondary to frequency coverage. | Select ADL5387ACPZ-R7 when modulator-only function is needed and external VVA/detector design is preferred. |
| TRF3705IRGZT | Lower 400–4000 MHz range; 12 dBm P1dB; integrated PLL/VCO; no detector; 32-pin QFN vs. 40-pin LFCSP. | Targets compact single-chip transceivers in 4G small cells; lacks standalone detector and VVA, limiting AGC autonomy. | Choose TRF3705IRGZT only when on-chip LO synthesis is required and detector/VVA functionality is implemented elsewhere. |
Compared with ADL5386ACPZ-R2, ADL5387ACPZ-R7 offers broader frequency coverage but removes integrated signal conditioning, while TRF3705IRGZT adds LO synthesis at the cost of detector/VVA capability-making ADL5386ACPZ-R2 uniquely balanced for infrastructure-grade AGC-enabled transmitters.

FAQ
What is the recommended LO drive level for ADL5386ACPZ-R2?
The ADL5386ACPZ-R2 is characterized at −7 dBm LO drive level, with specified operation from −13 dBm to +2 dBm. At 350 MHz output, −7 dBm delivers optimal sideband suppression (−46 dBc) and carrier feedthrough (−38 dBm). Driving below −13 dBm risks degraded quadrature accuracy; exceeding +2 dBm may cause LO port compression or reliability concerns per absolute maximum ratings.
Can ADL5386ACPZ-R2 operate without the integrated VVA?
Yes, ADL5386ACPZ-R2 can operate with the VVA disabled: tie TADJ to VPOS to disable the detector section, leave VDET/VCTL open, and route MODOUT directly to the next stage. The modulator functions independently-the VVA and detector are fully decoupled blocks sharing only supply and ground. Performance metrics like P1dB and sideband suppression remain unchanged.
How is temperature compensation implemented in ADL5386ACPZ-R2?
Temperature compensation in ADL5386ACPZ-R2 is applied to the logarithmic detector via the TADJ pin: a 22.1 kΩ resistor to ground sets the compensation current for frequencies across the 50–2200 MHz band. This resistor corrects detector slope drift over temperature, maintaining ±1 dB accuracy. The TEMP pin provides a separate analog voltage (1.45 V @ 27°C, −4.6 mV/°C) for system-level thermal monitoring or software compensation.
What baseband input biasing is required for ADL5386ACPZ-R2?
ADL5386ACPZ-R2 baseband inputs (IBBP/IBBN/QBBP/QBBN) require external 500 mV dc bias-no internal biasing is provided. Each pair accepts 1.4 Vp-p differential sine wave drive, resulting in 700 mVp-p per pin. Input impedance is high (>100 kΩ), so bias networks must source/sink <±60 μA. AC coupling capacitors are mandatory; improper biasing causes severe carrier leakage and sideband asymmetry.
Is ADL5386ACPZ-R2 pin-compatible with earlier ADL538x variants?
No, ADL5386ACPZ-R2 is not pin-compatible with ADL5380/ADL5382/ADL5385. It features a unique 40-lead LFCSP_VQ layout with dedicated ATTI/ATTO, VDET/VCTL, and TADJ pins not present in prior generations. Pin count, function allocation, and die architecture differ significantly-migration requires PCB redesign and layout validation per Analog Devices' AN-1119 application note.
