MAX2065 - Serial/ Parallel-Controlled Analog/Digital VGA

General Description

The MAX2065 high-linearity, analog/digital variablegain amplifier (VGA) is designed to operate in the 50MHz to 1000MHz frequency range with two independent attenuators (see the Typical Application Circuit).

Key Features

  • include 22dB amplifier gain (amplifier only), 6.5dB NF at maximum gain (includes attenuator insertion losses), and a high OIP3 level of +42dBm. Each of these features makes the MAX2065 an ideal VGA for numerous receiver and transmitter.

19-3131; Rev 0; 3/08 50MHz to 1000MHz High-Linearity, Serial/ Parallel-Controlled Analog/Digital VGA General Description The MAX2065 high-linearity, analog/digital variablegain amplifier (VGA) is designed to operate in the 50MHz to 1000MHz frequency range with two independent attenuators (see the Typical Application Circuit). The digital attenuator is controlled as a slave peripheral using either the SPI™-compatible interface or a parallel bus with 31dB total adjustment range in 1dB steps. An added feature allows “rapid-fire” gain selection between each of four steps, preprogrammed by the www.DataSheet4U.com user through the SPI-compatible interface. The 2-pin control allows the user to quickly access any one of four customized attenuation states without reprogramming the SPI bus.
