GENERAL DESCRIPTION
transmit variable gain amplifier (TxVGA) provides
an interface for radio frequency (RF) digital-to-analog converters
(DACs), transceivers, and systems on a chip (SoC) to power
amplifiers (PAs). Integrated balun and hybrid couplers allow
high performance RF capability over a frequency range of
0.5 GHz to 1.0 GHz.
To optimize performance vs. power level, the
includes
a voltage variable attenuator (VVA), high linearity amplifiers, and
a digital step attenuator (DSA). The devices integrated into the
are programmable via a 4-wire serial port interface (SPI).
This user guide describes the evaluation board and software for
the
. For full details, see the
data sheet,
which must be consulted when using the evaluation board. The
ADL6316-EVALZ evaluation board is fabricated with FR-370HR,
Rogers 4350B in four layers.
