1212 0.5 dB LSB GaAs MMIC DUAL 6-BIT DIGITAL VARIABLE GAIN AMPLIFIER, DC -
4 GHz Functional Diagram Electrical Specifications, TA = +25° C,
50 Ohm System Vdd = +5V, Vcc = +5V The HMC743ALP6CE is ideal for: ? Cellular/3G Infrastructure ? WiBro, WiMAX &
LTE/4G ? Microwave Radio &
VSAT ? Test Equipment and Sensors ? IF &
RF Applications -45 to +18 dB Gain Control in 0.5 dB Steps Power-up State Selection High Output IP3: +33 dBm TTL/CMOS Compatible Serial Control ±0.25 dB Typical Gain Step Error Single +5V Supply
40 Lead 6x6 mm SMT Package:
36 mm2 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. Parameter Min. Typ. Max. Min. Typ. Max. Units Frequency Range
