INDUSTRY'S
FIRST MONOLITHIC RF VGA
The
ADL5330 is the industry’s first single-chip RF
amplifier/attenuator (VGA) that operates at RF power
levels for wireless infrastructure equipment. The ADL5330
is also the first monolithic VGA to provide broadband
operation from 1 MHz to 3 GHz with a precision 60-dB
linear-in-decibel gain-control range. These features,
critical to demanding radio designs, have never before
been available within a single IC.

Unlike
conventional discrete solutions that require many external
components, the single-chip ADL5330 integrates broadband
amplifiers and attenuators, offering considerable savings
in board area, component count, and solution cost as
compared to discrete implementations. The precision
linear-in-decibel control interface further simplifies
and eases circuit design.
The
ADL5330 provides 60-dB dynamic gain and attenuation
(approximately 20 dB gain and –40 dB attenuation), an
output power level of 22 dBm (1-dB compression point),
an output third-order intercept (OIP3) of 31 dBm at
1 GHz, and a noise figure of 8 dB.
The
ADL5330 is an ideal companion to Analog Devices’s I/Q
modulators (AD8345, AD8346, and AD8349) and power detectors
(AD8313, AD8314, and AD8362). Using the ADL5330 in conjunction
with these devices can enable a complete transmit signal
path. The ADL5330 single-chip VGA costs $4.98
per unit in 1,000-piece quantities.
