RF Amplifiers

Analog Devices’ extensive family of single-ended, fixed-gain RF amplifiers can be used as gain blocks, low noise amplifiers (LNA), intermediate frequency amplifiers, diver amplifiers and differential amplifiers from DC to RF, microwave and millimeter wave bands. ADI’s engineers have continually pushed the limits of innovation on RF amplifiers with its industry-leading performance. ADI’s RF amplifiers are fully specified over frequency, temperature and supply voltage, giving designers the solution for use in a wide variety of applications.

Analog Design Tool: ADIsimRF™

ADIsimRF is an easy-to-use RF signal chain calculator. It calculates Cascaded Gain, Noise Figure, IP3, P1dB and Power Consumption. The number of stages can be varied up to a maximum of 20. Stages can be easily inserted, removed or temporarily muted.

Fully Differential Amplifiers

Beginning with the industry’s first differential amplifier, Analog Devices has developed a portfolio of fully differential amplifiers to meet your performance requirements.

Gain Blocks

ADI’s extensive family of single-ended input/output, fixed-gain RF amplifiers can be used from dc to microwave and include gain blocks, low noise amplifiers, and driver amplifiers.

Low Noise Amplifiers

ADI’s extensive family of single-ended input/output, fixed-gain RF amplifiers includes technology such as low noise amplifiers, gain blocks, and intermediate frequency amplifiers.

Power Amplifiers

Analog Devices MMIC-based GaN and GaAs power amplifiers cover the low hundred MHz frequency range up through and including components in the W band (75 GHz to 110 GHz).

RF Amplifiers Bias Controllers

RF amplifier bias controllers generate a regulated drain voltage and actively adjusts the gate voltage of an external amplifier to achieve constant bias current.

Wideband Distributed Amplifiers

Analog Devices GaAs MMIC-based wideband distributed amplifiers cover the dc to 65 GHz frequency range in various ultrawide bandwidths.
