HMC960LP4E 射频放大器

HMC960LP4E

射频放大器 VGA, Dual Differential

DC - 100 MHz DUAL Digital  Variable Ga in AmplifieR with Driver

General Description

The HMC960LP4E is a digitally programmable dual

channel variable gain amplifier. It supports discrete

gain steps from 0 to 40 dB in precise 0.5 dB steps.

It features a glitch free architecture to provide

exceptionally smooth gain transitions. The device

has matched gain paths which provide excellent

quadrature balance over a wide signal bandwidth.

The HMC960LP4E provides an SPI programmable

input impedance of 100 Ω differential or 400 Ω

differential (default).

Externally controlled common mode output feature

enables the HMC960LP4E to provide a flexible output

interface to other parts in the signal path.
