Description

The ADL5335 is a digital gain amplifier (DGA) optimized foruse in wireless transmitters. A differential input and single-ended output facilitates a balun free connection between thebroadband integrated transceivers with differential outputs andthe 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 stepsize of 0.5 dB. The ADL5335 also features a fast attack functionwhere the gain can rapidly increase or decrease by theapplication of a single pulse.The use of a thermometer-based digital step attenuator (DSA)ensures that gain changes are fundamentally glitch free. TheADL5335 is packaged in a 4 mm ? 4 mm, 16-lead LFCSP. Afully populated evaluation board and system demonstrationplatform (SDP)-based control software are available.Applications RF power control and calibration in wireless transmitters
