The ADL5335 is a digital gain amplifier (DGA) optimized for
use in wireless transmitters. A differential input and singleended 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 Rev. 0 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. …
