The ADL5335 is a digital gain amplifier (DGA) optimized for use in wireless transmitters. A differential input and single- ended output facilitates a balun free connection between the broadband integrated transceivers with differential outputs and the RF gain blocks and drivers amplifiers with single-ended inputs.
The gain is programmable via a standard Analog Devices, Inc., serial peripheral interface (SPI) port from a maximum gain of 12.0 dB down to a minimum gain of −8.0 dB with a gain step size of 0.5 dB. The ADL5335 also features a fast attack function where the gain can rapidly increase or decrease by the application of a single pulse.
The use of a thermometer-based digital step attenuator (DSA) ensures that gain changes are fundamentally glitch free. The ADL5335 is packaged in a 4 mm × 4 mm, 16-lead LFCSP. A fully populated evaluation board and system demonstration platform (SDP)-based control software are available.

Tools & Simulations
ADIsimRF is an easy-to-use RF signal chain calculator. Cascaded gain, noise, distortion and power consumption can be calculated, plotted and exported for signal chains with up to 50 stages. ADIsimRF also includes an extensive data base of device models for ADI’s RF and mixed signal components.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
