HMC742ALP5E v01.1213 0.5 dB LSB GaAs MMIC 6-BIT DIGITAL VARIABLE GAIN AMPLIFIER, 70 MHz - 4 GHz Typical Applications Features The HMC742ALP5E is ideal for: -19.5 to 12 dB Gain Control in 0.5 dB Steps Power-up State Selection Cellular/3G Infrastructure High Output IP3: +39 dBm WiBro / WiMAX / 4G TTL/CMOS Compatible Microwave Radio & VSAT Serial, Parallel, or latched Parallel Control Test Equipment and Sensors 0.25 dB Typical Gain Step Error IF & RF Applications Single +5V Supply 2 32 Lead 5x5 mm SMT Package: 25 mm Functional Diagram General Description The HMC742ALP5E is a digitally controlled variable gain amplifier which operates from 70 MHz to 4 GHz, and can be programmed to provide from -19.5 dB attenuation, to 12 dB of gain, in 0.5 dB steps. The HMC742ALP5E delivers noise figure of 4 dB in its maximum gain state, with output IP3 of up to +39 dBm in any state. The dual mode gain control interface accepts either a three-wire serial input or a 6 bit parallel word. The HMC742ALP5E also features a user selectable power up state and a serial output for cascading other serially controlled Hittite components. The HMC742ALP5E is housed in an RoHS compliant 5x5 mm QFN leadless package, and requires minimal external components. Electrical Specifications, T = +25 C, 50 Ohm System Vdd = +5V, Vs= +5V A Min.
