Product details
Overview
LTC5590IUH#PBF from Analog Devices (formerly Linear Technology) is a dual-channel, high-dynamic-range, downconverting RF mixer optimized for 600MHz–1.7GHz RF input with 700MHz–1.5GHz LO support. It delivers 8.7dB conversion gain, 26dBm IIP3, and 9.7dB noise figure at 900MHz, enabling high-selectivity LTE/GSM receiver front-ends with lossy IF filtering and minimal board space. Its independent channel enable pins and low-power mode support power-aware MIMO infrastructure designs.
For engineers reviewing the LTC5590IUH#PBF datasheet, LTC5590IUH#PBF pinout, LTC5590IUH#PBF application, or LTC5590IUH#PBF equivalent, this page provides verified RF performance data, validated dual-channel isolation specs, confirmed QFN-24 package mapping, real-world blocking resilience (15.6dB NF under 5dBm blocker), and authoritative alternative part comparisons for wireless infrastructure receiver design.
Technical Context
The LTC5590IUH#PBF integrates two identical passive double-balanced mixer cores with dedicated LO buffer amplifiers, differential IF amplifiers, and independent enable logic per channel. Each channel features single-ended 50Ω-matched RF and LO inputs, differential open-collector IF outputs (IFA+/IFA−, IFB+/IFB−), and internal transformer-based biasing.
It supports both high-side (fLO = fRF + fIF) and low-side (fLO = fRF − fIF) LO injection, with LO input matched across all enable states to prevent source pulling. Performance is specified over –40°C to 105°C with 3.3V/5V dual-supply flexibility and 0dBm nominal LO drive.

Pinout & Package
24-lead (5mm × 5mm) plastic QFN package with exposed thermal pad (Pin 25 = GND). Requires soldering of exposed pad to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RFA, RFB (1, 6) | Single-ended RF inputs | 50Ω-matched primary transformer inputs; require DC-blocking capacitors if RF source has DC offset. |
| CTA, CTB (2, 5) | RF transformer center-taps | Internally biased at 1.2V; bypass caps improve IIP3 but optional for most applications. |
| LO (16) | Single-ended LO input | 50Ω-matched across all enable states; accepts 0dBm ±6dBm drive; requires DC-blocking capacitor. |
| ENA, ENB (14, 17) | Independent channel enables | Logic-high (>2.5V) activates channel; <0.3V disables; <10μA input current enables low-power control. |
| ISEL (18) | Low-current mode select | High (>2.5V) reduces total supply current to ~305mA while maintaining usable RF performance. |
| IFA+, IFA−, IFB+, IFB− (9,10,21,22) | Differential IF outputs | Open-collector; require external pull-up inductors/transformers to set output impedance and DC bias. |
| VCCA, VCCB (12, 19) | Mixer/LO supply | 3.3V supply pins for LO buffers and mixer bias; each draws ~94mA typical. |
| VCCIF (9,10,21,22) | IF amplifier supply | 3.3V or 5V configurable supply for IF amps; impacts P1dB and noise figure trade-offs. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent shutdown | ENA/ENB pins allow per-channel power gating-critical for TDD/FDD mode switching in 4G/5G base stations. |
| LO input impedance stability | 50Ω match maintained whether channels are on/off-eliminates LO source frequency pulling during state transitions. |
| High-side LO support | Validated operation with fLO = fRF + fIF (e.g., 1090MHz LO for 900MHz RF → 190MHz IF)-simplifies filter placement and image rejection. |
| Blocking resilience | 15.6dB NF under 5dBm blocker at 800MHz - preserves sensitivity in co-located multi-band deployments. |
| Thermal robustness | θJC = 7°C/W with soldered exposed pad - enables reliable operation at full power in sealed outdoor enclosures. |
| IF output flexibility | Differential open-collector outputs support transformer-coupled 50Ω single-ended IF or active termination for DC-coupled baseband. |

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 | Higher RF range (1.2–2.5GHz), lower IIP3 (22dBm), no integrated IF amps, requires external IF gain. | Better suited for higher-frequency TDD-LTE bands; lacks on-chip IF amplification, increasing external component count. | Select when operating above 1.7GHz or when discrete IF gain control is preferred over integrated amplification. |
| MAX19997AETX+ | Wider RF range (400MHz–3.8GHz), lower conversion gain (6.5dB), higher NF (11.5dB), same QFN-32 package. | Offers broader frequency coverage but trades off sensitivity and gain; requires more board area due to larger footprint. | Select when multi-band flexibility across sub-1GHz to 3.5GHz is prioritized over peak LTE receiver performance metrics. |
Compared with HMC1040LP4CE and MAX19997AETX+, the LTC5590IUH#PBF delivers superior IIP3 and NF within its 600–1.7GHz band, integrates IF amplifiers to reduce external components, and uses a smaller 5mm QFN package-making it optimal for space-constrained, high-performance LTE macro and micro base station receivers.

FAQ
What is the recommended LO drive level for optimal performance of the LTC5590IUH#PBF?
The LTC5590IUH#PBF is characterized for 0dBm LO drive, with guaranteed performance across ±6dBm (–4dBm to +6dBm). At 0dBm, it achieves 8.7dB conversion gain, 26dBm IIP3, and 9.7dB NF at 900MHz. Deviations outside this range degrade linearity and noise figure-so the LTC5590IUH#PBF should be driven within this window using a stable, low-phase-noise synthesizer.
Can the LTC5590IUH#PBF support both high-side and low-side LO injection?
Yes, the LTC5590IUH#PBF supports both configurations: high-side LO (fLO = fRF + fIF) for RF inputs from 600–1100MHz, and low-side LO (fLO = fRF – fIF) for 1100–1600MHz RF. The datasheet specifies distinct AC performance curves for each mode-e.g., 27.5dBm IIP3 at 1200MHz under low-side LO-confirming validated operation across both schemes in the LTC5590IUH#PBF.
How does the ISEL pin affect power consumption and RF performance in the LTC5590IUH#PBF?
When ISEL is pulled high (>2.5V), the LTC5590IUH#PBF enters low-current mode, reducing total supply current from 484mA to 305mA (typical) while retaining usable RF performance: conversion gain drops by ~0.5dB and IIP3 by ~1.5dB at 900MHz. This trade-off makes the LTC5590IUH#PBF suitable for power-sensitive applications like remote radio heads where thermal headroom is limited.
What is the function of the CTA and CTB pins on the LTC5590IUH#PBF?
CTA (Pin 2) and CTB (Pin 5) are the center-taps of the internal RF transformer secondaries for Channels A and B. They provide access to the transformer midpoint for optional bypass capacitor connection-improving IIP3 in some high-linearity applications. Each pin has a nominal 1.2V DC bias and must be DC-isolated from ground and VCC; the LTC5590IUH#PBF datasheet confirms their role in optimizing third-order distortion suppression.
Is the LTC5590IUH#PBF pin-compatible with other devices in the LTC559x family?
No-the LTC5590IUH#PBF is not pin-compatible with LTC5591/LTC5592/LTC5593. While all share the same 24-lead QFN package outline, pin functions differ significantly: e.g., LTC5591 assigns Pin 1 to VCCA, whereas LTC5590IUH#PBF uses Pin 1 for RFA. The datasheet's Pin Configuration diagram explicitly confirms unique signal mapping per device, so PCB layout must be tailored to the LTC5590IUH#PBF.
