Product details
Overview
LTC5592 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. It delivers 8.3dB conversion gain, 27.3dBm IIP3, and 9.8dB noise figure at 2.35GHz with 0dBm LO drive, enabling LTE/WiMAX diversity receivers requiring high linearity and channel isolation.
For engineers reviewing the LTC5592 datasheet, LTC5592 pinout, LTC5592 application, or LTC5592 equivalent, this page provides verified RF/IF performance data, validated dual-channel shutdown control, low-power mode operation, 47dB channel-to-channel isolation, and QFN-24 package layout guidance - all critical for MIMO infrastructure receiver design.
Technical Context
The LTC5592 integrates two independent mixer channels sharing a single LO input, each comprising a passive double-balanced core, differential IF buffer amplifier, LO buffer amplifier, and bias circuitry. RF and LO inputs are single-ended and internally matched to 50Ω across 1.6–2.7GHz and 1.5–2.5GHz ranges respectively.
It supports both low-side (fLO = fRF − fIF) and high-side (fLO = fRF + fIF) LO injection, with differential IF outputs (IFA+/IFA−, IFB+/IFB−) referenced to dedicated ground pins (IFGNDA/IFGNDB). Independent ENA/ENB enable control and ISEL-selectable low-power mode (1.3W → 0.8W) provide system-level power management.

| IFA+, IFA−, IFB+, IFB− (9,10,21,22) | Differential IF outputs | Open-collector; require external inductors or transformer center-taps for proper termination and DC bias |
| VCCA, VCCB (12, 19) | Mixer/LO supply | 3.3V regulated supply; 99.5mA typical per pin; bypass with 1µF + 22pF near each pin |

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 (1.7–4.2GHz), higher P1dB (+15.5dBm), but no integrated IF amplifiers - requires external IF gain stages | Requires additional IF amplification and filtering; larger solution size and higher power budget | Choose when wider RF coverage or higher input compression is required, and board space allows external IF chain |
| ADRF6612 | Integrated synthesizer and IF VGA; 1.5–2.7GHz RF range; 24.5dBm IIP3; consumes 1.8W - no independent channel shutdown | Eliminates need for external LO source but lacks per-channel enable control and has higher power draw | Choose when LO synthesis integration is prioritized over power scalability and channel independence |
Compared with HMC1040LP4CE and ADRF6612, the LTC5592 uniquely combines dual-channel independent enable control, integrated IF amplifiers, and selectable low-power mode - making it optimal for thermally constrained, high-isolation MIMO receivers where solution size and dynamic power management are critical.

FAQ
What is the recommended LO drive level for optimal performance of the LTC5592?
The LTC5592 is specified for 0dBm LO drive level across its 1.5–2.5GHz range. At 2.35GHz RF input, this yields 8.3dB conversion gain, 27.3dBm IIP3, and 9.8dB noise figure. Deviating below –4dBm or above +6dBm degrades linearity and increases LO leakage; the LTC5592 datasheet confirms 0dBm as the nominal condition for all key AC specs.
Can the LTC5592 operate with high-side LO injection, and what is the supported RF range in that configuration?
Yes, the LTC5592 supports high-side LO injection (fLO = fRF + fIF) for RF inputs from 1.6GHz to 2.3GHz. In this mode, with 190MHz IF and 2.14GHz LO, it achieves 8.3dB conversion gain and 25.1dBm IIP3 at 1.95GHz RF. The datasheet explicitly defines this range in the AC Electrical Characteristics table under "High Side LO Downmixer Application".
How does the ISEL pin affect the performance of the LTC5592, and what is the trade-off in low-power mode?
When ISEL is pulled high (>2.5V), the LTC5592 enters low-power mode, reducing total supply current from 489mA to 312mA. This lowers power consumption from 1.3W to 0.8W but trades off 1.5–2dB in IIP3 and ~0.5dB in noise figure across the RF band - verified in the Low Power Mode AC Characteristics section of the LTC5592 datasheet.
What is the function of the CTA and CTB pins on the LTC5592, and how should they be used in layout?
CTA (Pin 2) and CTB (Pin 5) are RF transformer secondary center-taps providing 1.2V internal bias. Adding a 4.7pF capacitor (C8A/C8B) from each to ground improves channel-to-channel isolation by up to 5dB at specific frequencies without degrading conversion gain or noise figure - as demonstrated in the Applications Information section and Figure 2 of the LTC5592 datasheet.
Is the LTC5592 compatible with 5V IF supply voltage, and what impact does it have on performance?
Yes, the LTC5592 supports VCCIF up to 5.3V. At 5V IF supply, input 1dB compression improves from 11.3dBm to 12.6dBm at 2.35GHz RF - a 1.3dB enhancement - while conversion gain and IIP3 remain unchanged. This is documented in the DC Electrical Characteristics table under "Input 1dB Compression" conditions for VCCIF = 3.3V vs 5V.
