The LTC6430-15 is a differential gain block amplifier designed to drive high resolution, high speed ADCs with excellent linearity beyond 1000MHz and with low associated output noise. The LTC6430-15 operates from a single 5V power supply and consumes only 800mW.

In its differential configuration, the LTC6430-15 can directly drive the differential inputs of an ADC. Using 1:2 baluns, the device makes an excellent 50Ω wideband balanced amplifier. While using 1:1.33 baluns, the device makes a high fidelity 50MHz to 1000MHz 75Ω CATV amplifier.

The LTC6430-15 is designed for ease of use, requiring a minimum of support components. The device is internally matched to 100Ω differential source/load impedance. On-chip bias and temperature compensation ensure consistent performance over environmental changes.

The LTC6430-15 uses a high performance SiGe BiCMOS process for excellent repeatability compared with similar GaAs amplifiers. All A-grade LTC6430-15 devices are tested and guaranteed for OIP3 at 240MHz. The LTC6430-15 is housed in a 4mm × 4mm, 24-lead, QFN package with an exposed pad for thermal management and low inductance. For a single-ended 50Ω IF gain block with similar performance, see the related LTC6431-15.

LTC6430-15 Demo Board | 50MHz to 1200MHz Parallel Connected, Boosted OIP3, ADC/IF Amplifier

Product Detail

Demonstration circuit 2090A features two LTC6430-15s differential ADC/IF Amplifier connected in parallel at the inputs and outputs, boosting the output third order intercept point (OIP3) and the output power each by about 3dB higher. The parallel connection reduces the differential input and output impedance by one-half so the composite amplifier has 50Ω differential input and output impedances, this demo circuit uses 1:1 balun transformers to convert the differential I/O impedances to 50Ω single-ended so that the DC2090A can be easily evaluated with most RF test equipment.
