Product details
Overview
LTC5510IUF#TRPBF from Analog Devices (formerly Linear Technology) is a high-linearity, wideband active mixer IC optimized for RF up- and down-conversion in 1MHz–6GHz systems. It delivers 1.5dB conversion gain, 27dBm OIP3 at 1575MHz, 11.6dB noise figure, and operates from 5V or 3.3V with shutdown control - enabling use in GPS L1-band receivers, cable infrastructure downlinks, and broadband wireless transceivers.
For engineers reviewing the LTC5510IUF#TRPBF datasheet, LTC5510IUF#TRPBF pinout, LTC5510IUF#TRPBF application, or LTC5510IUF#TRPBF equivalent, this page provides verified technical context, package mapping to the 4mm × 4mm QFN-16, confirmed pin functions, real-world performance trade-offs between 5V/3.3V operation, and two validated alternative mixers for frequency-agile receiver designs.
Technical Context
The LTC5510IUF#TRPBF integrates a double-balanced active mixer core, input buffer, and high-speed LO amplifier - all optimized for wideband impedance matching via 1:1 baluns. Its differential architecture supports both single-ended and differential LO drive at only 0dBm, minimizing external driver complexity while maintaining >55dB IN–LO isolation and <–50dBm LO-in leakage across 20MHz–3.3GHz.
It features on-chip temperature monitoring (TEMP pin), programmable bias adjustment (IADJ), and rail-compatible enable logic (EN). The device maintains stable conversion gain (–0.006 dB/°C typical) and OIP3 over –40°C to 105°C, with distinct high-side/low-side LO modes selected internally based on input frequency range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 1MHz–6GHz RF input; 1MHz–6.5GHz LO; 1MHz–6GHz output - supports multi-band cellular, GNSS, and broadband test equipment without re-design. |
| Conversion Gain | 1.5dB typical at fIN=900MHz, fOUT=1575MHz, 5V - eliminates need for post-mixer gain stages in many LNA+mixer architectures. |
| OIP3 | 27dBm at fOUT=1575MHz, 5V - enables handling of strong interferers in base station front-ends and spectrum analyzers. |
| Noise Figure | 11.6dB at fOUT=1575MHz - balances sensitivity and linearity for wideband receivers where cascaded NF matters. |
| Supply & Power | 5V or 3.3V operation; 105mA total supply current at 5V; 2.5μA shutdown current - supports dual-rail system integration and low-power standby. |
| LO Drive | 0dBm differential LO required - reduces external LO amplifier cost and board space vs. +10dBm alternatives. |
| Input P1dB | 11dBm at 5V - allows direct connection to moderate-gain LNAs without attenuation or compression risk. |
Pinout & Package
Package: 16-lead (4mm × 4mm) plastic QFN with exposed thermal pad (Pin 17 = GND). Requires soldering exposed pad to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN+, IN– (2, 3) | Differential RF Input | Internally biased at 1.6V DC; requires AC coupling; matched 50Ω input from 30MHz–>3GHz enables direct balun interface. |
| LO+, LO– (14, 15) | Differential LO Input | Biased at 1.7V DC; accepts 0dBm LO; internal selection of HS/LS mode based on fIN - no external configuration needed. |
| OUT+, OUT– (10, 11) | Differential IF Output | Requires external LC matching or transformer center-tap to 50Ω; 201Ω||0.6pF differential impedance at 1500MHz. |
| EN (5) | Enable Control | Logic-high (>1.8V) enables full operation; logic-low (<0.5V) reduces supply current to 2.5μA - supports fast TDD switching. |
| TEMP (1) | Die Temperature Monitor | Anode of on-die diode with 30Ω series resistor; voltage drops –1.8mV/°C at 10μA - enables closed-loop thermal compensation. |
| IADJ (8) | Bias Current Adjustment | Pull-down resistor sets mixer quiescent current; floating = default 5V bias point; allows optimization of OIP3 vs. power trade-off. |
| VCC1, VCC2 (6, 7) | LO & Bias Supply | 41mA typical draw; must be decoupled with 10nF caps near pins; shared rail simplifies power routing. |
| GND (9, 12, 13, 17) | RF/Power Ground | Exposed pad (Pin 17) is primary thermal path; all GND pins must connect to solid RF ground plane - critical for LO suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Wideband 50Ω Input Matching | Input return loss >11dB from 30MHz–3GHz - eliminates external matching networks in most GNSS and LTE bands. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar wideband active mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| HMC1040LP3DE | Wider 10MHz–6GHz RF range; higher 30dBm OIP3; requires +7dBm LO drive; 24-lead 4×4mm QFN. | Better for ultra-high-dynamic-range test equipment; less suitable for battery-powered GNSS due to LO power and package size. | Select HMC1040LP3DE when OIP3 >29dBm is mandatory and LO power budget allows +7dBm; avoid if board space or LO drive capability is constrained. |
| MAX2062ETX+ | 20MHz–3GHz RF range; 25.5dBm OIP3; 5V-only; integrated LO buffer; 32-pin TQFN. | Optimized for fixed-frequency infrastructure; lacks TEMP/IADJ pins; larger footprint limits portable SDR use. | Select MAX2062ETX+ for cost-sensitive, narrowband 2G/3G/LTE base stations where 3GHz upper limit suffices and thermal monitoring is not required. |
Compared with HMC1040LP3DE and MAX2062ETX+, the LTC5510IUF#TRPBF uniquely balances ultra-wide bandwidth (1MHz–6GHz), ultra-low LO drive (0dBm), and integrated diagnostics (TEMP, IADJ) in a compact 16-pin QFN - making it optimal for field-deployable, multi-band, thermally variable RF systems.

FAQ
What is the minimum LO drive level required for specified performance of the LTC5510IUF#TRPBF?
The LTC5510IUF#TRPBF achieves its published conversion gain, OIP3, and noise figure with only 0dBm differential LO drive across 1MHz–5GHz. Driving below –3dBm degrades OIP3 by up to 4dB and increases NF by ~1.5dB; therefore, 0dBm is the recommended minimum for full datasheet compliance in the LTC5510IUF#TRPBF.
Can the LTC5510IUF#TRPBF operate from a 3.3V supply without performance loss?
The LTC5510IUF#TRPBF supports 3.3V operation but with measurable trade-offs: OIP3 drops ~3.5dB (to 23.3dBm), input P1dB decreases to 8.9dBm, and supply current reduces to 94mA. These shifts are documented in the 3.3V characterization tables - the LTC5510IUF#TRPBF remains fully functional but is optimized for 5V for maximum linearity.
How is the temperature monitor (TEMP pin) used in the LTC5510IUF#TRPBF?
The TEMP pin (Pin 1) connects to an on-die diode with a 30Ω series resistor. By forcing a constant 10μA current and measuring voltage (697mV at 25°C, –1.8mV/°C coefficient), die temperature is derived. This enables real-time correction of gain/linearity drift in the LTC5510IUF#TRPBF - no external sensor or calibration is needed.
Does the LTC5510IUF#TRPBF require external matching components for 50Ω operation?
Yes - while the LTC5510IUF#TRPBF input is 50Ω-matched from 30MHz–>3GHz, it requires external 1:1 baluns for single-ended signal interfacing. The output demands LC matching or center-tapped transformers to convert its 201Ω||0.6pF differential impedance to 50Ω - these components are shown in the typical application circuit (Figure 1) of the LTC5510IUF#TRPBF datasheet.
What is the function of the IADJ pin on the LTC5510IUF#TRPBF?
The IADJ pin (Pin 8) adjusts the internal mixer bias current via an external pull-down resistor. Leaving it floating sets default 5V operation; adding a resistor (e.g., 4.75kΩ for 5V, 1.8kΩ for 3.3V) fine-tunes OIP3 vs. power trade-off. This allows optimization of the LTC5510IUF#TRPBF for specific linearity or efficiency targets without changing the IC itself.
