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, and 3.0dB noise figure across 20MHz–2000MHz bandwidth - enabling clean signal conditioning in LTE, CATV, and wideband IF sampling systems.
For engineers reviewing the LTC6430-15 datasheet, LTC6430-15 pinout, LTC6430-15 application, or LTC6430-15 equivalent, this page provides verified specifications, package-aware pin functions, real-world differential interface guidance, and validated alternatives for 50Ω/75Ω balanced amplifier and ADC driver designs.
Technical Context
The LTC6430-15 employs a SiGe BiCMOS process with internal 100Ω differential input/output matching and on-chip bias/temperature compensation. Its single-stage Darlington-based gain block minimizes stability risk while achieving >2.75VP-P linear output swing and unconditional stability up to 1.2GHz (S11/S22 < –15dB).
It operates from a single 5V supply (4.75–5.25V), consumes 160mA total supply current, and integrates internal DC biasing - eliminating external bias networks. The device supports direct differential ADC interfacing or 50Ω/75Ω balanced amplification via external baluns (1:2 or 1:1.33), with performance guaranteed over –40°C to +85°C case temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| OIP3 @ 240MHz (A-grade) | 50.0 dBm - enables high-dynamic-range reception in multi-carrier OFDM systems without front-end attenuation |
| Differential Gain | 15.2 dB - fixed, flat gain across 20–2000 MHz supports wideband IF sampling without gain compensation |
| Noise Figure | 3.0 dB @ 240MHz - low added noise preserves SNR when driving high-resolution ADCs |
| Bandwidth | 20 MHz to 2000 MHz (–3dB) - covers LTE bands (700–800 MHz), CATV (50–1000 MHz), and IF sampling up to 1 GHz |
| Input/Output Impedance | 100Ω differential, internally matched - eliminates external matching networks for standard differential interfaces |
| Supply | Single 5V (4.75–5.25V), 800mW total power - simplifies power delivery vs. dual-supply RF amplifiers |
| Output Swing | >2.75 VP-P linear - drives 16-bit ADCs (e.g., LTC22xx series) without clipping at full scale |
Pinout & Package
Package: 4mm × 4mm, 24-lead plastic QFN with exposed thermal pad (Pin 25 = GND). Requires soldering of exposed pad to PCB ground plane for thermal management and low-inductance RF grounding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN (24) | Positive differential input | Internally biased to 2V DC; requires DC-blocking capacitor; forms 100Ω diff pair with –IN |
| –IN (7) | Negative differential input | Internally biased to 2V DC; requires DC-blocking capacitor; forms 100Ω diff pair with +IN |
| +OUT (18) | Positive differential output | Requires RF choke or center-tapped transformer to VCC for DC bias feed and AC isolation |
| –OUT (13) | Negative differential output | Requires RF choke or center-tapped transformer to VCC for DC bias feed and AC isolation |
| VCC (9, 22) | Positive supply input | Two pins provided for layout flexibility; both connect internally; bypass with 1000pF + 0.1µF |
| GND (8, 14, 17, 23, 25) | Ground terminals | Multiple GND pins + exposed pad (25) must connect to low-inductance PCB ground plane |
| T_DIODE (16) | Temperature monitoring diode | Forward-biased to ground with ≤1mA; voltage drop indicates die temperature for thermal management |
| DNC (1–6, 10–12, 15, 19–21) | Do Not Connect | Must remain unconnected and floating; connection degrades RF performance and linearity |
Key Features
| Feature | Design Value |

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, 2400MHz BW, 22.5dBm P1dB, requires external matching; no integrated temp compensation | Higher bandwidth but lower OIP3 (42dBm @ 200MHz); suited for ultra-wideband test equipment vs. CATV/LTE | Select ADL5562 when >2GHz bandwidth is mandatory and external matching is acceptable |
| LTC6431-15 | Single-ended 50Ω I/O, same gain/OIP3 specs, identical SiGe process and A-grade testing | Designed for legacy 50Ω single-ended signal chains; eliminates need for input balun | Choose LTC6431-15 when interfacing with single-ended sources (e.g., mixers, filters) without differential conversion |
Compared with ADL5562 and LTC6431-15, the LTC6430-15 uniquely combines 100Ω differential matching, on-chip temperature compensation, and guaranteed A-grade OIP3 - making it optimal for production CATV and LTE infrastructure where linearity consistency and minimal external components are critical.

FAQ
What is the guaranteed OIP3 performance of the LTC6430-15 across frequency?
The LTC6430-15 A-grade guarantees minimum OIP3 of 46.6 dBm at 240MHz and 45.3 dBm at 700MHz into a 100Ω differential load. Typical performance reaches 50.0 dBm at 240MHz and remains above 43.5 dBm at 1000MHz, supporting high-dynamic-range RF front ends. All A-grade units undergo 100% production OIP3 testing at 240MHz.
Can the LTC6430-15 drive a 50Ω single-ended ADC input directly?
No - the LTC6430-15 has 100Ω differential input/output impedance and requires external 1:2 baluns to interface with 50Ω single-ended systems. For direct 50Ω single-ended drive, Analog Devices recommends the pin-compatible LTC6431-15, which shares identical gain, OIP3, and SiGe process but features single-ended I/O.
How should the exposed thermal pad (Pin 25) of the LTC6430-15 be connected?
The exposed pad (Pin 25) of the LTC6430-15 must be soldered to the PCB ground plane using multiple thermal vias. This provides low-inductance RF grounding and thermal dissipation for the 800mW device. Failure to connect the pad degrades S11/S22 match, increases junction temperature, and risks reliability failure under continuous operation.
Does the LTC6430-15 require external DC biasing components?
No - the LTC6430-15 integrates internal bias generation and temperature compensation. Only external DC-blocking capacitors on +IN/–IN, RF chokes on +OUT/–OUT, and VCC bypass capacitors (1000pF + 0.1µF) are required. This eliminates bias resistors, current mirrors, or external references needed by competing RF amplifiers.
What balun ratio is recommended for 75Ω CATV applications with the LTC6430-15?
For 75Ω CATV amplifier applications, a 1:1.33 balun is recommended to transform the LTC6430-15's native 100Ω differential impedance to 75Ω system impedance. This configuration maintains high fidelity across 50–1000MHz and is explicitly validated in the LTC6430-15 datasheet for CATV use cases.
