Sunnyvale, Calif.óMaxim Integrated Products has introduced the MAX2063, calling it the industry's only fully programmable, multi-state, dual-channel, digital IF/RF variable-gain amplifier (VGA).
The MAX2063 provides "rapid-fire" gain selection for four customized attenuation states per path, fast 25ns digital switching, and low digital VGA amplitude overshoot/undershoot. It is intended for the "fast-attack" automatic gain control (AGC) circuits found in all 2.5G, 3G, 4G wireless infrastructure transceivers, including GSM/EDGE, CDMA, WCDMA, LTE, and WiMAX applications.
