Resumen del producto

The LMH6514SQE is a high performance digitally controlled Variable Gain Amplifier for use with IF sampling receivers. 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 dynamic range. When used in conjunction with a high speed ADC, system dynamic range can be extended by up to 42dB. 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 200R resistive. The output impedance is either 200 or 400R and is user selectable. Unique internal architecture allows use with both single ended and differential input signals.
