CLC522

Wideband Variable-Gain Amplifier

Features

General Description

■ 330MHz signal bandwidth: A_vmax= 2

■ 165MHzgain-controlbandwidth

■ 0.3° to 60MHz linear phase deviation

■ 0.04%(-68dB)signal-channelnon-linearity

■ >40dBgain-adjustmentrange

The CLC522 variable gain amplifier (VGA) is a dc-coupled, two-

quadrantmultiplierwithdifferentialvoltageinputsandasingle-ended

voltageoutput. Twoinputbuffersandanoutputoperationalamplifer

VGA system that does not require external buffering.

Applications

■ Variableattenuators

■ Pulseamplitudeequalizers

■ HFmodulators

■ Automatic gain control & leveling loops

■ Videoproductionswitching

■ Differential line receivers

■ Voltage controlled filters

The CLC522's maximum gain may be set anywhere over a nominal

range of 2V/V to 100V/V. The gain control input then provides

attenuation from the maximum setting. For example, set for a

maximumgainof100V/V, theCLC522willprovidea100V/Vto1V/V

to -0.98V.

Gain vs. Gain Control Voltage (V )

Set at a maximum gain of 10V/V, the CLC522 provides a 165MHz

signalchannelbandwidthanda165MHzgaincontrolbandwidth.Gain

nonlinearity over a 40dB gain range is 0.5% and gain accuracy at

_max= 10V/V is typically ±0.3%.
