HMC743ALP6CE v00.1212 0.5 dB LSB GaAs MMIC DUAL 6-BIT DIGITAL VARIABLE GAIN AMPLIFIER, DC - 4 GHz Features Typical Applications The HMC743ALP6CE is ideal for: -45 to +18 dB Gain Control in 0.5 dB Steps Power-up State Selection Cellular/3G Infrastructure High Output IP3: +33 dBm WiBro, WiMAX & LTE/4G TTL/CMOS Compatible Serial Control Microwave Radio & VSAT 0.25 dB Typical Gain Step Error Test Equipment and Sensors Single +5V Supply IF & RF Applications 2 40 Lead 6x6 mm SMT Package: 36 mm Functional Diagram General Description The HMC743ALP6CE is a digitally controlled variable gain amplifier which operates from DC to 4 GHz, can be programmed to provide 63 dB of gain control in 0.5 dB steps and delivers output IP3 of up to +33 dBm. The gain control interface accepts a three wire serial input word and allows independent or simultaneous control of two 6-bit digital attenuators. The HMC743ALP6CE also features a user selectable power up state and a serial output for cascading other serially controlled Hittite products. The HMC743ALP6CE is housed in an RoHS compliant 6x6 mm QFN leadless package, and requires minimal external components.
