Product details
Overview
ADRF6658BCPZ from Analog Devices is a wideband dual-channel RF downconverter IC integrating two active Gilbert-cell mixers and two digitally controlled IF amplifiers (DGAs) in a single 48-lead LFCSP package. It operates from 690 MHz to 3.8 GHz RF input, delivers up to +26.5 dB voltage conversion gain, achieves 29 dBm input IP3 at minimum DGA gain, and supports differential or single-ended LO inputs for cellular base station receiver front-ends.
For engineers reviewing the ADRF6658BCPZ datasheet, ADRF6658BCPZ pinout, ADRF6658BCPZ application, or ADRF6658BCPZ equivalent, this page provides verified technical context, real-world performance boundaries, validated pin functions, confirmed alternative options for infrastructure receiver designs, and supply-chain-ready procurement details.
Technical Context
The ADRF6658BCPZ implements two independent doubly balanced mixer cores with internal tunable baluns-programmable via Register 13 bits DB12–DB7 (COUT) and DB12–DB10 (CIN)-to suppress harmonics and improve RF input return loss across 690–3800 MHz. Each mixer drives a 300 Ω differential output into a dedicated IF DGA stage.
Its dual IF DGAs-based on ADL5201/ADL5202 architecture-offer 0.5 dB gain steps over 31.5 dB range, fixed 100 Ω differential output impedance, and support both SPI (3-wire) and parallel 6-bit latch control (A0–A5/B0–B5). Gain conformance error is ±0.05 dB per step, phase conformance error ≤0.5°, and power-up time from standby is 100 ns typical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Input Frequency Range | 690 MHz to 3.8 GHz - enables coverage of W-CDMA, LTE, WiMAX, and PCS bands without external tuning. |
| Voltage Conversion Gain Range | −5 dB to +26.5 dB - 31.5 dB digitally programmable range with 0.5 dB resolution supports dynamic IF level optimization. |
| Input IP3 (High Linearity Mode) | 29 dBm at minimum DGA gain - ensures robust blocker rejection in dense multi-carrier base station environments. |
| SSB Noise Figure | 13 dB at 1950 MHz, max DGA gain - balances sensitivity and linearity for high-dynamic-range receiver chains. |
| Channel Isolation | 52 dB - prevents crosstalk between dual Rx paths in active antenna or diversity receiver systems. |
| Power Consumption | 440 mA (high linearity mode), 260 mA (low power mode) - configurable trade-off between performance and thermal budget. |

Pinout & Package
ADRF6658BCPZ is housed in a 7 mm × 7 mm, 48-lead LFCSP package with exposed pad (EP) requiring low-impedance grounding via multiple vias. Pin functions are validated per Analog Devices' Rev. A datasheet (pages 8–9).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| MIXARFIN / MIXBRFIN | Single-ended 50 Ω RF input | Accepts broadband RF signal; internal balun converts to differential for mixer core. |
| LOIN+ / LOIN− | Differential or single-ended LO input | Supports flexible clocking: terminate LOIN− to ground for single-ended mode; AC-couple both for differential. |
| MIXAOUT+/MIXAOUT− / MIXBOUT+/MIXBOUT− | Differential mixer outputs (300 Ω) | DC-coupled, require external pull-up inductors matched to IF frequency band. |
| DGAAIN+/DGAAIN− / DGABIN+/DGABIN− | Differential DGA inputs (300 Ω) | Interface directly with mixer outputs; no external matching needed. |
| IFAOUT+/IFAOUT− / IFBOUT+/IFBOUT− | Differential IF outputs (100 Ω) | Fixed-impedance, ready for direct connection to ADC drivers or filters. |
| CHAEN / CHBEN | Channel enable control | Hardware power-down control: logic high enables channel; 100 ns wake-up time. |
| LATCHA / LATCHB | Parallel DGA gain latch control | Edge-triggered strobe for A0–A5/B0–B5 6-bit gain codes; enables fast gain updates without SPI overhead. |
| DATA / CLK / LE / SDO | 3-wire SPI interface | 32-bit serial register map supports configuration, readback, and daisy-chaining of multiple devices. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable RF baluns | Register-controlled CIN/COUT tuning (Register 13 bits DB12–DB7) optimizes input return loss across 690–3800 MHz band. |
| Dual independent power-down | CHAEN/CHBEN pins allow per-channel disable with 100 ns recovery-critical for TDD or burst-mode operation. |
| Flexible gain control interface | Simultaneous support for SPI (3-wire) and parallel 6-bit latch (A0–A5/B0–B5) enables low-latency or low-pin-count system integration. |
| High-accuracy DGA stepping | ±0.05 dB gain conformance and ≤0.5° phase conformance per 0.5 dB step ensure predictable I/Q path matching. |
| Thermally robust packaging | 7 mm × 7 mm LFCSP with exposed pad achieves θJA = 27.26°C/W-enables high-density RF module layouts without forced cooling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel RF downconverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADRF6612ACPZ | Single-channel, 400–3800 MHz RF range, lower max gain (+20 dB), no integrated baluns. | Suitable only for non-diversity or space-constrained single-path designs; lacks dual-channel isolation and balun programmability. | Select when cost or board area is prioritized over dual-path performance and harmonic suppression. |
| LMX2594RHAT | Wideband PLL synthesizer (not a mixer); no IF amplification, no DGA, no RF/IF conversion function. | Cannot replace ADRF6658BCPZ-used for LO generation only; requires external mixer and IF chain. | Use only as complementary LO source-not as functional substitute for ADRF6658BCPZ's integrated downconversion role. |
Compared with ADRF6658BCPZ, ADRF6612ACPZ offers reduced integration and narrower feature set for simpler receivers, while LMX2594RHAT serves an entirely different signal-generation function and cannot fulfill the downconversion, amplification, or channel-isolation requirements of the original design.

FAQ
What is the RF input impedance of the ADRF6658BCPZ?
The ADRF6658BCPZ features a nominal 50 Ω single-ended RF input impedance at MIXARFIN and MIXBRFIN pins, achieved via internal V-to-I converter and tunable balun structure. This matches standard RF front-end filter and amplifier interfaces without external matching networks.
Does the ADRF6658BCPZ support both differential and single-ended LO inputs?
Yes, the ADRF6658BCPZ supports both modes: connect LOIN+ and LOIN− differentially with AC coupling for optimal phase noise and rejection, or drive LOIN+ with AC-coupled signal while terminating LOIN− to ground for single-ended operation-both configured via register settings.
What is the maximum IF output frequency supported by the ADRF6658BCPZ?
The ADRF6658BCPZ supports IF output frequencies up to 520 MHz (f−3dB), verified across temperature and supply variations. Its differential 100 Ω IF outputs maintain flat group delay and low distortion through this band, enabling direct interface with high-speed ADCs.
How does the ADRF6658BCPZ achieve channel isolation of 52 dB?
The ADRF6658BCPZ achieves 52 dB channel isolation through physical separation of RF/LO/IF signal paths, independent bias networks, and differential topology with common-mode rejection-measured at 1950 MHz RF and 2231 MHz LO with maximum DGA gain per channel.
Can the ADRF6658BCPZ operate from a single 3.3 V supply?
Yes, the ADRF6658BCPZ operates from a single 3.3 V ±5% supply applied to DVDD, with all other supplies (MIXAVDD, MIXBVDD, DGAAVDD, DGABVDD, LOVDD) tied to DVDD. No auxiliary voltages are required for full functionality.
