Product details
Overview
LTC6430-15 from Analog Devices (formerly Linear Technology) is a high-linearity, fixed-gain differential RF/IF amplifier optimized as an ADC driver for 16-bit, high-speed data converters. It delivers 15.2dB gain, 50.0dBm OIP3 at 240MHz into 100Ω differential load, 3.0dB noise figure, and >2.75VP-P linear output swing across 20MHz–2000MHz bandwidth, operating from a single 5V supply with 800mW power consumption.
For engineers reviewing the LTC6430-15 datasheet, LTC6430-15 pinout, LTC6430-15 application, or LTC6430-15 equivalent, this page provides verified specifications, package layout, real-world use cases in CATV, LTE, and IF signal chains, and validated alternative options for differential wideband amplifier selection.
Technical Context
The LTC6430-15 implements a SiGe BiCMOS-based differential gain block with internal 100Ω differential input/output matching, on-chip bias and temperature compensation, and unconditionally stable operation. Its architecture uses a single-stage Darlington-pair input with shunt-series feedback to simultaneously optimize impedance match, linearity, and bandwidth.
It operates as a true differential amplifier-rejecting common-mode noise and suppressing second-harmonic distortion-while supporting flexible interface configurations: direct drive to differential ADC inputs, 1:2 balun-based 50Ω balanced amplification, or 1:1.33 balun-based 75Ω CATV amplification from 50MHz to 1000MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | 15.2dB typical differential power gain - enables precise signal level setting before ADC sampling without external attenuation or gain staging. |
| OIP3 @ 240MHz (A-grade) | 50.0dBm - supports high-dynamic-range reception in multi-carrier OFDM systems with minimal intermodulation distortion. |
| Noise Figure | 3.0dB - preserves SNR in front-end IF amplification stages where low-noise performance directly impacts system sensitivity. |
| Bandwidth | 20MHz to 2000MHz (–3dB) - covers LTE bands (700–800MHz), CATV (50–1000MHz), and wideband IF applications without re-tuning. |
| Output Swing | >2.75VP-P linear - drives 16-bit ADCs such as LTC2268 or AD9643 to full-scale without clipping or compression artifacts. |
| Supply | Single 5V rail (4.75–5.25V), 160mA total current - simplifies power design versus dual-supply RF amplifiers and reduces BOM count. |
| Package | 4mm × 4mm, 24-lead QFN with exposed thermal pad - enables compact RF layout with low-inductance grounding and efficient heat dissipation. |
Pinout & Package
Package: 24-lead plastic QFN (4mm × 4mm), exposed pad (Pin 25) connected to GND for thermal and RF grounding. All ground pins (Pins 8, 14, 17, 23, and exposed pad 25) must be soldered to PCB ground plane via multiple vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN (24) | Differential positive input | Internally biased at 2V DC; requires DC-blocking capacitor; matched to 100Ω diff source impedance. |
| –IN (7) | Differential negative input | Internally biased at 2V DC; requires DC-blocking capacitor; complements +IN for common-mode rejection. |
| +OUT (18) | Differential positive output | Requires RF choke or center-tapped transformer to VCC for DC bias feed and AC isolation; drives 100Ω diff load. |
| –OUT (13) | Differential negative output | Paired with +OUT; identical biasing and interface requirements; enables true differential signaling to ADC. |
| VCC (9, 22) | Positive supply input | Two dedicated pins for 5V supply routing flexibility; each must be bypassed with 1000pF + 0.1µF ceramic capacitors. |
| T_DIODE (16) | On-die temperature sensor | Forward-biased diode (≤1mA) whose voltage drop correlates with junction temperature; enables thermal monitoring in sealed modules. |
| GND (8, 14, 17, 23, 25) | Ground reference | Multiple low-inductance paths required; exposed pad (25) is mandatory GND connection for RF stability and thermal performance. |
| DNC (1–6, 10–12, 15, 19–21) | No-connect terminals | Must remain floating; solder mask coverage recommended to prevent accidental shorts or parasitic coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Internally matched 100Ω differential I/O | Eliminates external matching networks from 20MHz–1700MHz, reducing layout complexity and component count in wideband designs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential RF amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADL5562 | 16.5dB gain, 2.8dB NF, 48.5dBm OIP3 @ 200MHz, 3.3V supply, 560mW power | Optimized for lower-voltage, lower-power systems; narrower bandwidth (3.5GHz max) but higher gain accuracy | Select ADL5562 when 3.3V supply and tighter gain tolerance (±0.3dB) are prioritized over 5V compatibility and ultra-wideband linearity. |
| LTC6409 | 20dB gain, 3.5dB NF, 42dBm OIP3 @ 100MHz, 5V supply, 750mW power, 100Ω diff I/O | Higher gain but lower OIP3 and narrower usable bandwidth (up to 1.3GHz); same QFN package footprint | Select LTC6409 only when system gain budget requires >15dB and OIP3 >45dBm is not mandatory - e.g., lower-tier IF stages. |
Compared with ADL5562 and LTC6409, the LTC6430-15 uniquely balances 5V operation, 50.0dBm OIP3, and 2GHz bandwidth in a thermally robust QFN, making it optimal for high-fidelity, wideband receiver front ends where linearity and supply simplicity are non-negotiable.

FAQ
What is the guaranteed OIP3 performance of the LTC6430-15 across temperature?
The A-grade LTC6430-15 is 100% tested for minimum 46.6dBm OIP3 at 240MHz and 25°C, with typical performance reaching 50.0dBm. Over the full –40°C to 85°C case temperature range, OIP3 remains ≥43.5dBm at 1000MHz and ≥45.3dBm at 700MHz per AC Electrical Characteristics tables. The on-chip temperature compensation maintains consistent linearity without external calibration.
Can the LTC6430-15 be used with a 3.3V supply?
No - the LTC6430-15 is specified only for 4.75V to 5.25V operation per Absolute Maximum Ratings and DC Electrical Characteristics. Supplying 3.3V will result in improper biasing, degraded gain, increased noise, and potential failure to meet OIP3 or P1dB specs. For 3.3V systems, consider the ADL5562 or LTC6406 as alternatives.
How should the exposed thermal pad (Pin 25) of the LTC6430-15 be connected on the PCB?
The exposed pad (Pin 25) must be soldered directly to the PCB ground plane using ≥9 thermal vias (0.3mm diameter, spaced ≤1mm apart) connecting to inner-layer ground planes. This ensures low-inductance RF grounding and thermal resistance (θJC = 40°C/W). Solder mask should cover via backside to prevent solder wicking, and copper weight ≥1 oz is recommended for heat spreading.
Does the LTC6430-15 support DC-coupled operation?
No - the LTC6430-15 is not designed for DC coupling. Its internal DC biasing (2V on +IN/–IN, open-collector output stage) creates a fixed common-mode offset mismatch between input and output. The lower frequency cutoff is limited by on-chip matching elements, and attempting DC coupling introduces instability and gain peaking below ~20MHz. AC coupling with ≥1000pF blocking capacitors is mandatory.
What balun is recommended for 75Ω CATV operation with the LTC6430-15?
For 75Ω CATV applications from 50MHz to 1000MHz, a 1:1.33 impedance ratio balun is required to transform the LTC6430-15's 100Ω differential output to 75Ω single-ended. Mini-Circuits' BAL-CT1-133+ or Marki Microwave's BAL-0007SMG are validated options. These maintain amplitude/phase balance <0.3dB/<2° across band and preserve the LTC6430-15's 47.5dBm OIP3 at 300MHz.
