HMC628LP4 / 628LP4E v07.0410 BiCMOS MMIC 5-Bit DIGITAL VARIABLE GAIN AMPLIFIER, 50 - 800 MHz Typical Applications Features The HMC628LP4(E) is ideal for: TTL/CMOS compatible serial, parallel or latched parallel control interface Cellular/3G Infrastructure High Output IP3: +35 dBm (At all gain settings) WiBro / WiMAX / 4G Wide Gain Control Range: 23 dB Microwave Radio & VSAT Power-up State Selection Test Equipment and Sensors 2 24 Lead 4x4 mm SMT Package: 16 mm IF & RF Applications Excellent State & Step Accuracy (0.05 dB) Functional Diagram General Description The HMC628LP4(E) is a digitally controlled variable gain ampl ifier which operates from 50 to 800 MHz, 12 and can be programmed to provide anywhere from 8 dB attenuation, to 15 dB of gain, in 1.0 dB steps. The HMC628LP4(E) delivers noise fi gure of 5 dB in its maximum gain state, with output IP3 of up to +35 dBm in any state. The dual mode control interface is CMOS/ TTL compatible, and accepts either a three wire serial input or a 5 bit parallel word. The HMC628LP4(E) also features a user selectable power up state and a serial output port for cascading other Hittite serial controlled components. The HMC628LP4(E) is housed in a RoHS compliant 4x4 mm QFN leadless package, and is available in three evaluation board con figurations, depending on the application frequency.
