Product details
Overview
LTC5566IUH#TRPBF from Analog Devices (formerly Linear Technology) is a dual-channel, wideband, downconverting RF mixer with integrated digital IF variable-gain amplifiers (DVGA). It delivers 12dB power conversion gain, 35dBm output IP3, and 15.5dB IF gain control in 0.5dB steps via SPI, targeting MIMO and diversity receivers operating from 300MHz to 6GHz.
For engineers reviewing the LTC5566IUH#TRPBF datasheet, LTC5566IUH#TRPBF pinout, LTC5566IUH#TRPBF application, or LTC5566IUH#TRPBF equivalent, key selection criteria include dual-channel isolation (>40dB), programmable RF input tuning, reduced-power mode operation, and differential IF output compatibility with baseband filters and ADC drivers in 4G/5G infrastructure.
Technical Context
The LTC5566IUH#TRPBF integrates two independent active mixers with on-chip RF transformers for 50Ω single-ended RF inputs and differential LO/IF interfaces. Each channel features a digitally programmable IF DVGA with precise 0.5dB gain resolution across 15.5dB range, controlled via 3-wire SPI or parallel logic.
It supports four pre-characterized RF bands (450MHz–4.5GHz), each optimized for specific LO-side injection and matching. Programmable RF tuning and a dedicated reduced-power mode enable adaptive power/performance trade-offs in real-time without external component changes.

Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel RF mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1040LP5E | Single-channel, 300MHz–6GHz mixer with 11dB conversion gain and 28dBm OIP3; no integrated IF VGA or programmable RF tuning. | Requires external IF gain control and matching components; suitable only for single-path or discrete dual implementations. | Select when lower cost and simpler control are prioritized over integrated gain tuning and dual-channel co-location. |
| ADL5375-05 | Quadrature modulator (not mixer); 700MHz–1GHz RF range; requires external LO generation and lacks RF tuning capability. | Designed for transmit path; incompatible with receive-side downconversion and IF filtering requirements of MIMO receivers. | Not a functional alternative-intended for upconversion, not downconversion; avoid for this application. |
Compared with HMC1040LP5E and ADL5375-05, the LTC5566IUH#TRPBF uniquely combines dual-channel integration, on-die IF gain control, and programmable RF matching in one package-reducing PCB area, component count, and calibration complexity in multi-antenna receiver systems.

FAQ
What is the RF frequency range supported by the LTC5566IUH#TRPBF?
The LTC5566IUH#TRPBF supports an RF input frequency range of 300MHz to 6GHz, validated across five pre-characterized bands (450MHz, 850MHz, 1.9GHz, 2.6GHz, and 3.6–4.5GHz) with optimized matching and performance metrics per band.
Does the LTC5566IUH#TRPBF require external RF matching components?
No-the LTC5566IUH#TRPBF integrates on-die RF transformers for 50Ω single-ended RF inputs and supports programmable RF input tuning via SPI or parallel control lines, eliminating the need for external matching networks in most standard 50Ω systems.
How is IF gain controlled on the LTC5566IUH#TRPBF?
The LTC5566IUH#TRPBF provides 15.5dB of IF gain control in precise 0.5dB steps through its 3-wire SPI interface; each channel's DVGA is independently programmable, enabling per-path AGC implementation without external DACs or op-amps.
What is the maximum supply current for the LTC5566IUH#TRPBF in full-power mode?
In full-power mode with both channels enabled, the LTC5566IUH#TRPBF draws up to 450mA from the 3.3V VCC supply (typical 384mA), as specified in the Electrical Characteristics table under "Supply Current (ICC)" conditions.
Is the LTC5566IUH#TRPBF pin-compatible with other devices in the LTC556x family?
No-while the LTC5566IUH#TRPBF shares the same 32-lead QFN package outline with some earlier Linear mixers, its pinout (e.g., dedicated T0/T1 tuning pins, dual IF output pairs, and PS control) is unique to the LTC5566 and not interchangeable with LTC5562, LTC5564, or other variants.
