250MHz to 4000MHz Dual, Analog Voltage Variable Attenuator
General Description
The MAX19790 dual, general-purpose analog voltage variable attenuator (VVA) is designed to interface with 50I systems operating in the 250MHz to 4000MHz frequency range. Each attenuator includes a control circuit that provides 22dB of attenuation range with a linear control slope of 10dB/V.
Both attenuators share a mon analog control and can be cascaded together to yield 44dB of total dynamic range, with a bined linear control slope of 20dB/V.
The IC is a monolithic device designed on one of Maxim’s proprietary SiGe BiCMOS processes. The device operates from a single +5.0V...
