19-5618; Rev 0; 12/10
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 fre-
quency 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 con-
figured to either optimize noise figure (NF) (ampli-
fier configured first) or OIP3 (amplifier last). The
device’s performance features include 24dB ampli-
fier 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 is available in a compact 48-pin TQFN
package (7mm x 7mm) with an exposed pad. Electrical
performance is guaranteed over the extended tempera-
ture range, from T C = -40 N C to +85 N C.
