HMC681ALP5E v00.0113 0.5 dB LSB GaAs MMIC 6-BIT DIGITAL VARIABLE GAIN AMPLIFIER w/ SERIAL CONTROL, DC - 1 GHz Typical Applications Features The HMC681ALP5E is ideal for: +13.5 dB to +45 dB Gain Control in 0.5 dB Steps High Output IP3: +36 dBm IF & RF Applications 0.25 dB Typical Gain Step Error Cellular/3G Infrastructure Single +5V Supply WiBro / WiMAX / 4G 2 32 Lead 5x5 mm SMT Package: 25 mm Microwave Radio & VSAT Test Equipment and Sensors Functional Diagram General Description The HMC681ALP5E is a digitally controlled variable gain amplifier which operates from DC to 1 GHz, and can be programmed to provide anywhere from 13.5 dB, to 45 dB of gain, in 0.5 dB steps. The HMC681ALP5E delivers noise figure of 2.8 dB in its maximum gain state, with output IP3 of up to +36 dBm in any state. This serially controlled digital VGA incorporates off chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. The HMC681ALP5E is housed in a RoHS compliant 5x5 mm QFN leadless package, and provides the user with a highly integrated solution. This functionality is also available with parallel control as the HMC626ALP5E. Electrical Specifications, T = +25 C, Vdd = Vs= P/S= +5V A Min. Typ. Max. Min. Typ. Max.
