Variable Gain Amp Integrates Nine Functions

Saving space in 2.5G, 3G, and 4G transceivers, the MAX2062 incorporates nine unique circuit functions and debuts as the industry's only fully programmable, multistate, dual-channel, analog-plus-digital IF/RF variable-gain amplifier (VGA). The device provides rapid-fire gain selection of four customized attenuation states per path, 25-ns digital switching, and very low digital VGA amplitude overshoot/undershoot. It serves as either an IF or RF all-purpose VGA, interfacing directly with 50? systems operating over the 50 MHz to 1 GHz frequency range. Alternately, the chip is configurable to provide a compromise between the two parameters. Available in a 48-pin TQFN package, prices start at $13.45 each/1,000.
