Overview
LMH6514 600 MHz, Digital Controlled, Variable Gain Amplifier January 24, 2008 LMH6514 600 MHz, Digital Controlled, Variable Gain Amplifier General Description The LMH6514 is a high performance, digitally controlled variable gain amplifier (DVGA).
It combines precision gain control with a low noise, ultra-linear, differential amplifier.
Typically, the LMH6514 drives a high performance ADC in a broad range of mixed signal and digital communication applications such as mobile radio and cellular base stations where automatic gain control (AGC) is required to increase system dywww.

com namic range.
When used in conjunction with a high speed ADC, system dynamic range can be extended by up to 42 dB.
The LMH6514 has a differential input and output allowing large signal swings on a single 5V supply.
It is designed to accept signals from RF elements and maintain a terminated impedance environment.
The input impedance is 200Ω resistive.
The output impedance is either 200Ω or 400Ω and...
