ADI’s extensive family of single-ended input/output, fixed-gain RF amplifiers can be used from dc to microwave and include a variety of applications.
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.
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.
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.
