Product details
Overview
LTC5592IUH#TRPBF from Analog Devices (formerly Linear Technology) is a dual-channel, high-dynamic-range, passive double-balanced downconverting mixer IC optimized for 1.6–2.7GHz RF input and 190MHz IF output in LTE/WiMAX infrastructure receivers. It delivers 8.3dB conversion gain, 27.3dBm IIP3, and 9.8dB noise figure at 2.35GHz with 0dBm LO drive, operating from 3.3V supply and supporting low-side or high-side LO injection.
For engineers reviewing the LTC5592IUH#TRPBF datasheet, LTC5592IUH#TRPBF pinout, LTC5592IUH#TRPBF application, or LTC5592IUH#TRPBF equivalent, key selection criteria include channel-to-channel isolation (>47dB), independent enable control (ENA/ENB), low-power mode (ISEL), 50Ω single-ended RF/LO matching, and differential IF output impedance (379Ω||2.2pF at 190MHz).
Technical Context
The LTC5592IUH#TRPBF integrates two identical mixer channels sharing one LO input, each comprising a passive double-balanced core, dedicated LO buffer amplifier, IF buffer amplifier, and bias/enable circuitry. RF and LO inputs are single-ended and internally matched to 50Ω across 1.5–2.5GHz LO and 1.6–2.7GHz RF bands.
It supports both low-side (fLO = fRF – fIF) and high-side (fLO = fRF + fIF) LO injection, with IF output frequency range of 5–500MHz. Differential IF outputs (IFA+/IFA–, IFB+/IFB–) require external termination via inductors or transformer center-taps, and bias adjust pins (IFBA/IFBB) allow fine-tuning of IF amplifier currents.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 1.6GHz to 2.7GHz - covers LTE Band 7 (2500–2690MHz), Band 40 (2300–2400MHz), and WiMAX 2.3–2.7GHz systems. |
| LO Frequency Range | 1.5GHz to 2.5GHz - enables flexible low-side or high-side injection with 0dBm drive level for optimal linearity. |
| Conversion Gain | 8.3dB at 2.35GHz - provides sufficient gain to drive lossy SAW/BAW IF filters without cascading amplifiers. |
| IIP3 | 27.3dBm at 2.35GHz - ensures robust blocking immunity in dense multi-carrier base station environments. |
| Noise Figure | 9.8dB at 2.35GHz - maintains receiver sensitivity despite high gain and wide bandwidth. |
| Channel Isolation | >47dB - prevents crosstalk between MIMO or diversity receiver paths. |
| Supply Current | 489mA max (3.3V) - total current across VCCA/VCCB/VCCIFA/VCCIFB pins under full operation. |
| Operating Temp | –40°C to 105°C - qualified for outdoor wireless infrastructure and industrial-grade baseband units. |
Pinout & Package
24-lead (5mm × 5mm) plastic QFN package with exposed thermal pad (Pin 25 = GND). Requires soldering 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 | Internally DC-grounded transformer primaries; require series DC-blocking capacitors (e.g., 22pF) and match to 50Ω with LO present. |
| CTA, CTB (2, 5) | RF transformer center-taps | Provide 1.2V internal bias; bypass caps (e.g., 4.7pF) optimize IIP3 and channel isolation without degrading gain or NF. |
| LO (16) | Single-ended LO input | 50Ω matched across all enable states; requires 2.2pF DC-blocking cap; drives dual LO buffers for both channels. |
| ENA, ENB (17, 14) | Independent channel enables | Logic-high (>2.5V) activates channel; logic-low (<0.3V) shuts down mixer/IF amp, reducing current to 500µA total. |
| ISEL (18) | Low-power mode select | High voltage enables reduced-current mode (312mA total), trading ~1.5dB gain and ~2dB IIP3 for 35% power savings. |
| IFA+, IFA–, IFB+, IFB– (9,10,21,22) | Differential IF outputs | Open-collector; require external pull-up inductors (e.g., 150nH) or transformer center-taps to set 379Ω||2.2pF impedance at 190MHz. |
| IFBA, IFBB (11, 20) | IF amplifier bias adjust | Set internal IF buffer current; typical 2.2V DC; floating or improper bias causes gain/NF degradation. |
| VCCA, VCCB (12, 19) | LO buffer & bias supplies | 3.3V regulated inputs; each draws ~99.5mA; require local 1µF + 22pF bypassing. |
| VCCIFA, VCCIFB (9,10,21,22) | IF amplifier supplies | Support 3.3V or 5V operation; higher voltage increases P1dB (e.g., +1.3dB at 5V vs 3.3V). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent mixer channels | Enables MIMO/diversity architectures with separate ENA/ENB control and no shared signal path coupling. |
| 50Ω RF/LO input matching | Eliminates external matching networks across 1.5–2.5GHz LO and 1.6–2.7GHz RF bands, reducing BOM and layout area. |
| 190MHz IF-optimized architecture | Delivers flat conversion gain (±0.14dB) and high IIP3 (27.3dBm) at 190MHz, aligning with common SAW filter center frequencies. |
| Low-side and high-side LO support | Allows system-level flexibility: low-side for simplicity (fLO = fRF – 190MHz), high-side for image rejection (fLO = fRF + 190MHz). |
| Thermal and supply robustness | Specified over –40°C to 105°C; maintains <±0.006dB/°C gain drift and stable IIP3/NF across full temperature range. |
| Integrated LO buffer amplifiers | Accepts 0dBm LO drive and isolates LO source from RF load variations, preventing frequency pulling during channel switching. |

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 |
|---|---|---|---|
| HMC8192LP5DE | Wider RF range (1.7–4.2GHz), higher IIP3 (30dBm), but requires 5V supply and lacks independent channel shutdown. | Better suited for 3.5GHz TDD-LTE and mmWave fronthaul where wider bandwidth and higher linearity outweigh power/complexity trade-offs. | Select when RF band exceeds 2.7GHz or IIP3 >28dBm is mandatory; avoid if 3.3V-only supply or per-channel enable is required. |
| LTC5591IUH#TRPBF | Narrower RF range (1.3–2.3GHz), lower IIP3 (25.4dBm), same 24-QFN package and pinout, but optimized for 1.9GHz PCS/WCDMA bands. | Preferred for W-CDMA Band I (1920–1980MHz) and TD-SCDMA where 2.3GHz+ coverage is unnecessary. | Drop-in replacement only for sub-2.3GHz applications; retains identical layout, biasing, and enable logic-ideal for platform reuse. |

FAQ
What is the recommended LO drive level for optimal performance of the LTC5592IUH#TRPBF?
The LTC5592IUH#TRPBF is optimized for 0dBm LO drive across its 1.5–2.5GHz LO range. Performance degrades outside ±6dBm: below –4dBm, conversion gain drops and noise figure rises; above +6dBm, LO-to-RF leakage increases and reliability risks emerge. The datasheet specifies 0dBm as the nominal condition for all key specs including IIP3 and NF.
Can the LTC5592IUH#TRPBF operate with a single 3.3V supply, or does it require dual supplies?
The LTC5592IUH#TRPBF supports both configurations: VCCA/VCCB (LO buffers) and VCCIFA/VCCIFB (IF amps) can be tied together to a single 3.3V rail, or operated separately with VCCIFA/VCCIFB at 5V to boost P1dB by ~1.3dB. Total supply current is 489mA max in dual-supply mode (3.3V + 5V), versus 401mA in single 3.3V mode.
How does the ISEL pin affect RF performance in the LTC5592IUH#TRPBF?
When ISEL is high (>2.5V), the LTC5592IUH#TRPBF enters low-power mode: total supply current drops from 489mA to 312mA, conversion gain decreases by ~1.5dB, and IIP3 falls by ~2dB, while noise figure increases by ~0.5dB. This trade-off is intentional for standby/idle states where power efficiency outweighs peak linearity.
What is the function of the CTA and CTB pins on the LTC5592IUH#TRPBF, and how should they be used?
CTA and CTB (Pins 2 and 5) are RF transformer secondary center-taps providing 1.2V internal bias. Adding a small capacitor (e.g., 4.7pF) from CTA/CTB to ground improves channel-to-channel isolation at specific RF frequencies with minimal impact on gain or noise. The capacitor must be placed within 2mm of the pin for effective HF decoupling.
Is the LTC5592IUH#TRPBF compatible with high-side LO injection, and what are the RF band limitations?
Yes, the LTC5592IUH#TRPBF supports high-side LO injection (fLO = fRF + fIF) for improved image rejection. However, the RF input range is limited to 1.6–2.3GHz in this mode (vs. 1.6–2.7GHz for low-side), as specified in the AC Electrical Characteristics table. At 190MHz IF, high-side operation restricts usable RF to 1.79–2.49GHz.
