Maxim Integrated Products introduces the MAX2065, the industry's only fully programmable, multistate, analog and digital IF/RF variable-gain amplifier (VGA). This single, easy-to-control device delivers an unparalleled combination of VGA performance and component integration. Operating at 50MHz to 1000MHz, the MAX2065 provides unique "rapid fire" gain selection for four customized attenuation states, fast 25ns digital switching, and very low digital VGA amplitude overshoot/undershoot. It is an ideal choice for "fast-attack" AGC (automatic gain control) circuits found in all 2.5G/3G/4G wireless infrastructure transceivers, including GSM/EDGE, CDMA, WCDMA, LTE, and WiMAX%u2122 applications. |
