Product details
Overview
ADL5375-15ACPZ-R7 from Analog Devices is a broadband quadrature modulator operating from 400 MHz to 6 GHz, accepting differential baseband inputs and a single-ended LO to generate a single-ended 50 Ω RF output. It features 1500 mV I/Q input bias level, ≥10 dBm output P1dB at 2.15 GHz, ≤−49.9 dBc sideband suppression at 900 MHz, and −157.1 dBm/Hz noise floor - enabling high-performance zero-IF LTE/WiMAX transmitters.
For engineers reviewing the ADL5375-15ACPZ-R7 datasheet, ADL5375-15ACPZ-R7 pinout, ADL5375-15ACPZ-R7 application, or ADL5375-15ACPZ-R7 equivalent, this page delivers verified specifications, functional pin mapping, real-world use cases in multiband wireless infrastructure, and validated alternative options for RF front-end design.
Technical Context
The ADL5375-15ACPZ-R7 implements a silicon-germanium bipolar-based quadrature modulation architecture with integrated LO phase splitter, delivering precise I/Q amplitude balance (≤0.11 dB) and quadrature error (≤0.21°) across 400 MHz–6 GHz. Its 750 MHz IQ 3dB bandwidth supports wide-baseband digital predistortion and multistandard operation without external IF filtering.
It operates from a single 4.75 V–5.25 V supply, draws 127 mA when enabled, and integrates output disable (DSOP) with 85 dB RF isolation. Baseband inputs require external 1500 mV DC bias and low-impedance drive; LO input accepts −6 dBm to +6 dBm single-ended signal with ≥10 dB return loss up to 3.3 GHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 400 MHz to 6 GHz - supports multiband cellular (GSM/EDGE/W-CDMA/TD-SCDMA), LTE, WiMAX, and satellite modem RF upconversion without band switching. |
| Output P1dB | ≥10.6 dBm at 2.15 GHz - enables direct drive of power amplifiers in small-cell BTS without intermediate gain stages. |
| Sideband Suppression | ≤−49.9 dBc at 900 MHz - reduces adjacent-channel interference in narrowband systems requiring <0.1% EVM. |
| Carrier Feedthrough | ≤−34.2 dBm at 2.15 GHz - minimizes DC offset-induced spectral regrowth in zero-IF architectures. |
| Noise Floor | −157.1 dBm/Hz at 900 MHz (20 MHz offset) - ensures >75 dB SFDR for wide-dynamic-range DAC-driven transmitters. |
| I/Q Input Bias | 1500 mV - matches high-voltage-output DACs (e.g., AD9144) without level-shifting circuitry. |
| Supply Voltage | 4.75 V to 5.25 V - compatible with standard 5 V system rails and LDOs with ±2.5% tolerance. |
Pinout & Package
ADL5375-15ACPZ-R7 uses a 24-lead, exposed-paddle, lead-free LFCSP_VQ package (4 mm × 4 mm × 0.85 mm). The exposed paddle must be soldered to ground for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| DSOP | Output Disable Control | Logic-high (≥2.0 V) disables RFOUT with 85 dB isolation; critical for TDD timing and power sequencing. |
| LOIP / LOIN | Local Oscillator Inputs | Single-ended LO: LOIP driven, LOIN AC-coupled to ground; differential mode requires balanced drive - determines LO rejection and phase noise floor. |
| IBBP / IBBN / QBBP / QBBN | Differential Baseband Inputs | High-impedance (60–100 kΩ), externally biased to 1500 mV; require 1 V p-p differential swing for nominal output - defines baseband interface complexity. |
| RFOUT | RF Output | Single-ended, 50 Ω internally matched; requires AC coupling to load - eliminates external matching networks in 50 Ω systems. |
| VPS1 / VPS2 | Power Supply Pins | Both pins connect to same 5 V rail with local 0.1 µF + 100 pF bypassing - ensures stable core bias under fast RF envelope transitions. |
| COMM (Pins 2,5,8,11,12,14,17,19,20,23) | Ground Reference Terminals | Must be low-impedance connected to PCB ground plane - critical for minimizing I/Q imbalance and LO leakage. |
Key Features
| Feature | Design Value |
|---|---|
| 750 MHz IQ 3dB Bandwidth | Enables direct sampling of 300+ MHz complex baseband signals (e.g., 100 MHz LTE carriers with guard bands) without analog interpolation. |
| 85 dB RF Output Isolation (DSOP) | Supports time-division duplex (TDD) operation by fully blanking RF during receive intervals - eliminates need for external RF switches. |
| ≤0.21° Quadrature Error @ 900 MHz | Maintains <−50 dBc image rejection across temperature, reducing DSP-side image cancellation complexity in zero-IF receivers. |
| 1500 mV I/Q Input Bias Level | Aligns with industry-standard high-voltage DAC outputs (e.g., AD9162/AD9164), eliminating external bias resistors or op-amp level shifters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quadrature modulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADL5375-05ACPZ-R7 | 500 mV I/Q input bias level; identical package, pinout, and RF specs - differs only in baseband interface voltage requirement. | Designed for lower-voltage DACs (e.g., AD9122); requires level-shifting circuitry when interfacing with 1500 mV-biased DACs. | Select ADL5375-05ACPZ-R7 only when baseband source provides 500 mV bias; otherwise ADL5375-15ACPZ-R7 avoids external bias network. |
| TRF372017IRGZT | 300–4000 MHz range; 1.8 V/3.3 V dual supply; integrated LO synthesizer; 12-bit SPI control - lacks 6 GHz coverage and 1500 mV bias. | Targets low-power, integrated transceivers (e.g., IoT gateways); not suitable for 5G FR1 or satellite L/S-band. | Choose TRF372017IRGZT for cost-sensitive, narrowband designs needing on-chip LO; ADL5375-15ACPZ-R7 remains preferred for broadband, high-linearity infrastructure. |
Compared with ADL5375-05ACPZ-R7, the ADL5375-15ACPZ-R7 eliminates external bias resistors when paired with high-voltage DACs, reducing layout area and component count; versus TRF372017IRGZT, it delivers 2× frequency range and 3.5 dB higher OIP3 for macro-cell and satellite applications demanding wide instantaneous bandwidth.

FAQ
What is the recommended LO drive level for ADL5375-15ACPZ-R7?
The ADL5375-15ACPZ-R7 specifies a typical LO drive level of 0 dBm single-ended, with an operational range of −6 dBm to +6 dBm. Drive outside this range degrades sideband suppression and carrier feedthrough; at 2150 MHz, optimal performance (≤−49.9 dBc sideband suppression) is achieved at 0 dBm. Always AC-couple LO into LOIP while grounding LOIN via capacitor for single-ended operation.
Does ADL5375-15ACPZ-R7 support differential LO input?
Yes, ADL5375-15ACPZ-R7 supports both single-ended and differential LO configurations. For differential mode, drive LOIP and LOIN with equal-amplitude, 180° out-of-phase signals through AC-coupling capacitors. Differential LO improves LO rejection by up to 10 dB compared to single-ended, directly enhancing carrier feedthrough performance in the ADL5375-15ACPZ-R7.
How is the 1500 mV I/Q input bias implemented in ADL5375-15ACPZ-R7?
The ADL5375-15ACPZ-R7 does not generate the 1500 mV bias internally; its baseband inputs (IBBP/IBBN/QBBP/QBBN) require external DC biasing to 1500 mV. This is typically achieved using resistor dividers from VPS or dedicated bias ICs. The 1500 mV level aligns with high-voltage DAC outputs, eliminating level-shifting op-amps and simplifying interface design for ADL5375-15ACPZ-R7.
What is the thermal resistance (θJA) of ADL5375-15ACPZ-R7, and how should the exposed paddle be handled?
The ADL5375-15ACPZ-R7 has a θJA of 54°C/W when the exposed paddle is soldered to a solid ground plane. The paddle must be connected to PCB ground via multiple thermal vias (minimum 4× 0.3 mm diameter) under the pad. Failure to properly ground the paddle increases junction temperature, risking reliability degradation and reduced P1dB - especially critical for ADL5375-15ACPZ-R7 in continuous-wave 5G transmission.
Can ADL5375-15ACPZ-R7 be used in 6 GHz unlicensed band (5.925–7.125 GHz) applications?
No - ADL5375-15ACPZ-R7 is characterized and guaranteed from 400 MHz to 6 GHz only. At 5.8 GHz, output return loss drops to −8.6 dB and P1dB falls to 4.4 dBm (per datasheet Table 1), indicating degraded matching and compression behavior beyond 6 GHz. For 6 GHz band operation, consider newer modulators like the ADRF6780, not ADL5375-15ACPZ-R7.
