50MHz to 1000MHz High-Linearity, Serial/Analog-Controlled VGA

Industry's Only Fully Programmable Analog VGA

Please check latest availability status for a specific part variant.


The MAX2067 high-linearity analog variable-gain amplifier (VGA) is a monolithic SiGe BiCMOS attenuator and amplifier designed to interface with 50Ω systems operating in the 50MHz to 1000MHz frequency range (see the Typical Application Circuit in the full data sheet). The analog attenuator is controlled using an external voltage or through the SPI™-compatible interface using an on-chip 8-bit DAC.

Because each stage has its own RF input and RF output, this component can be configured to either optimize NF (amplifier configured first), or OIP3 (amplifier last). The device's performance features include 22dB amplifier gain (amplifier only), 4dB NF at maximum gain (includes attenuator insertion loss), and a high OIP3 level of +43dBm. Each of these features makes the MAX2067 an ideal VGA for numerous receiver and transmitter applications.

In addition, the MAX2067 operates from a single +5V supply with full performance, or a single +3.3V supply with slightly reduced performance, and has an adjustable bias to trade current consumption for linearity performance. This device is available in a compact 40-pin thin QFN package (6mm x 6mm) with an exposed pad. Electrical performance is guaranteed over the extended temperature range (TC = -40°C to +85°C).
