Product details
Overview
LTC5593IUH#TRPBF from Analog Devices (formerly Linear Technology) is a dual-channel, high-dynamic-range, 2.3GHz–4.5GHz RF downconverting mixer with integrated IF amplifiers. It delivers 8.5dB conversion gain, 27.7dBm IIP3, and 9.5dB noise figure at 2500MHz, operating from 3.3V with 1.3W total power consumption. It serves as the core RF-to-IF signal translation element in LTE/WiMAX diversity receivers requiring high channel isolation and low LO leakage.
For engineers reviewing the LTC5593IUH#TRPBF datasheet, LTC5593IUH#TRPBF pinout, LTC5593IUH#TRPBF application, or LTC5593IUH#TRPBF equivalent, key selection criteria include RF/LO frequency alignment (2.3–4.5GHz RF / 2.1–4.2GHz LO), differential IF output impedance (274Ω||2.4pF), independent channel shutdown control, and QFN-24 (5mm × 5mm) thermal performance with exposed GND pad.
Technical Context
The LTC5593IUH#TRPBF implements two fully independent, single-ended RF and LO input mixers with on-chip IF amplifiers, supporting both low-side and high-side LO injection. Its architecture enables simultaneous operation of dual receive paths with 52dB channel isolation at 2500MHz and <–33dBm LO-to-RF leakage.
It features programmable low-power mode (ISEL pin), independent ENA/ENB shutdown per channel, and matched 50Ω RF/LO inputs across all operating modes. The device maintains ±0.25dB conversion gain flatness over 60MHz IF bandwidth and supports 5–600MHz IF output frequencies with external matching.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel downconverting mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1040LP4CE | Single-channel, 2.2–4.2GHz, 24.5dBm IIP3, 11.5dB NF, requires external IF amplification | Lacks integrated IF amps and dual-channel integration; needs two units plus external gain blocks for equivalent functionality | Select when board space permits discrete IF amplification and higher LO drive (>+10dBm) is available |

FAQ
What RF and LO frequency ranges does the LTC5593IUH#TRPBF support?
The LTC5593IUH#TRPBF supports RF input frequencies from 2.3GHz to 4.5GHz and LO frequencies from 2.1GHz to 4.2GHz. This range covers LTE Bands 7 (2.5–2.69GHz), 38 (2.57–2.62GHz), 41 (2.496–2.69GHz), and WiMAX 3.5GHz (3.4–3.6GHz) and 5.8GHz (5.725–5.85GHz) bands when used with appropriate IF filtering. Operation is validated across this full range per datasheet AC performance curves.
Does the LTC5593IUH#TRPBF require external IF amplification?
No, the LTC5593IUH#TRPBF integrates dual high-gain IF amplifiers - one per channel - eliminating the need for external IF gain stages. Each IF amplifier drives a differential output (IFA+/IFA– and IFB+/IFB–) with 274Ω||2.4pF impedance, requiring only external AC coupling and termination. This integration reduces component count, board area, and noise contribution compared to discrete mixer + amplifier solutions.
How does the low-power mode (ISEL) affect performance of the LTC5593IUH#TRPBF?
When ISEL = high, the LTC5593IUH#TRPBF enters low-power mode, reducing total supply current from 493mA (1.3W) to 316mA (0.8W). This trades off 0.3–0.5dB conversion gain, ~1.5dB IIP3 reduction, and ~1dB NF increase across the 2.3–3.8GHz band - verified in datasheet Figures G19–G45. The mode retains full functionality including independent channel shutdown and LO/RF matching.
What is the recommended PCB layout practice for the exposed pad on the LTC5593IUH#TRPBF?
The exposed pad (Pin 25) of the LTC5593IUH#TRPBF must be soldered directly to a solid PCB ground plane to ensure thermal reliability and electrical performance. Analog Devices specifies ≥8 thermal vias (0.3mm diameter, filled or capped) connecting the pad to inner/outer ground layers. Inadequate thermal connection risks junction temperature exceeding 150°C under full load, degrading long-term reliability and parametric performance.
Can the LTC5593IUH#TRPBF operate with high-side or low-side LO injection?
Yes, the LTC5593IUH#TRPBF supports both high-side and low-side LO injection configurations. For low-side LO: fLO = fRF – fIF; for high-side LO: fLO = fRF + fIF. Datasheet AC performance tables (pages 5–6, 10–15) provide separate characterization for both modes across 2.3–4.0GHz RF, confirming stable conversion gain, IIP3, and NF in either configuration with 190MHz IF.
