GENERAL DESCRIPTION
The
variable gain amplifier operating from 100 MHz to 4000 MHz.
The VGA integrates two high performance amplifiers and a
digital step attenuator (DSA). Amplifier 1 (AMP1) is an
internally matched gain block amplifier with 20 dB gain, and
Amplifier 2 (AMP2) is a broadband ¼ W driver amplifier. The
DSA is 6-bit with a 31.5 dB gain control range, 0.5 dB steps, and
±0.25 dB step accuracy. The attenuation of the DSA can be
controlled using a serial or parallel interface.
The gain block and DSA are internally matched to 50 Ω at their
inputs and outputs, and all three internal devices are separately
biased. The separate bias allows all or part of the
used, which allows for easy reuse throughout a design. The
pinout of the
¼ W driver amplifier to be first, giving the VGA maximum
flexibility in a signal chain.
The
supply ranging from 4.75 V to 5.25 V. The VGA is packaged in a
thermally efficient, 5 mm × 5 mm, 32-lead LFCSP and is fully
specified for operation from −40°C to +85°C. A fully populated
evaluation board is available.
