HMC681LP5 / 681LP5E 0.5 d B LSB Ga As MMIC 6-BIT DIGITAL VARIABLE GAIN AMPLIFIER w/ SERIAL CONTROL, DC - 1 GHz v00.0508 Typical .. Applications Features +13.5 d B to +45 d B Gain Control in 0.5 d B Steps High Output IP3: +36 d Bm ±0.25 d B Typical Gain Step Error Single +5V Supply 32 Lead 5x5mm SMT Package: 25mm2 The HMC681LP5(E) is ideal for: - IF & RF Applications - Cellular/3G Infrastructure - Wi Bro / Wi MAX / 4G - Microwave Radio & VSAT - Test Equipment and Sensors VARIABLE GAIN AMPLIFIERS - SMT Functional Diagram General Description The HMC681LP5(E) is a digitally controlled variable gain amplifier which operates from DC to 1 GHz, and can be programmed to provide anywhere from 13.5 d B, to 45 d B of gain, in 0.5 d B steps. The HMC681LP5(E) delivers noise figure of 2.8 d B in its maximum gain state, with output IP3 of up to +36 d Bm 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 HMC681LP5(E) is housed in a Ro HS pliant 5x5 mm QFN leadless package, and provides the user with a highly integrated solution. This functionality is also available with parallel control as the HMC626LP5(E). Electrical Specifi cations, TA = +25° C, Vdd = Vs= P/S= +5V Min.
