Gain Blocks

Gain blocks are general-purpose broadband amplifiers that operate from low frequencies up to 6 GHz. All devices are 50 Ω internally matched with integrated internal bias circuitry, therefore minimizing the need for external components. ADI's gain blocks are fully ESD rated at 1 kV Class 1C or higher, and available in the smallest footprint LFCSP packaging.

Chart 1

All of the amplifiers are fully characterized over frequency, temperature, supply voltage, and part-to-part variation.


Low Noise Amplifiers (LNA)

As the first amplifier in the receive path, LNAs are a critical component for defining overall system performance and must be able to successfully amplify very low level signals without adding a significant amount of noise. ADI's LNA family sets an industry performance benchmark by operating from 400 MHz to 4 GHz while achieving a low noise figure with the optimum amount of gain and current consumption. The new LNA family includes integrated active bias circuitry, requires minimal external matching components, and is available in the smallest footprint LFCSP packaging.

Chart 2

Evaluation boards are available that enable the user to optimize the LNA across the desired frequency range of interest.


Intermediate Frequency Amplifiers (IFA)

Designed to operate in the IF frequency range typically below 500 MHz, ADI's family of single- and dual-channel IFAs are fully specified and characterized to support applications across the most commonly used IF frequencies of 70, 140, 190, 240, and 380 MHz. The new IFA amplifier family provides the highest linearity specifications and is supplied within the smallest footprint LFCSP packaging. Furthermore, ADI’s IFAs integrate active bias circuitry, require minimal external matching components and support 1 kV Class 1C ESD.

Chart 3

High linearity and low noise figures, within the smallest footprint packages on the market.


Driver Amplifiers

ADI's driver amplifier family offers the highest linearity for a given output power to enable low distortion, and high output drive, directly to the power amplifier stages. This family offers unprecedented flexibility with both narrow- and broadband solutions that incorporate internal active biasing. The narrow-band parts are also internally matched to further reduce the external component count. The broadband drivers enable the user to tune the amplifier with a minimal number of external components to a desired frequency range, with industry-leading linearity and minimal current consumption.

Chart 4

These amplifiers can be driven harder and remain linear, with minimum distribution, while requiring few external components.
