MAX2064

MAX2064 Dual 50MHz to 1000MHz High-Linearity, Serial/Analog-Controlled VGA General Description The MAX2064 high-linearity, dual analog variable-gain amplifier (VGA) operates in the 50MHz to 1000MHz frequency range. Each analog attenuator is controlled using an external voltage, or through the SPI-compatible interface using an on-chip 8-bit DAC. Since each of the stages has its own external RF input and RF output, this component can be configured to either optimize noise figure (NF) (amplifier configured first) or OIP3 (amplifier last). The device’s performance features include 24dB amplifier gain (amplifier only), 4.4dB NF at maximum gain (includes attenuator insertion losses), and a high OIP3 level of +41dBm. Each of these features makes the device an ideal VGA for multipath receiver and transmitter applications. In addition, the device operates from a single +5V supply with full performance, or a +3.3V supply for an enhanced power-savings mode with lower performance. The device i...
