HMC680LP4 / 680LP4E
v03.0609 BiCMOS MMIC 5-BIT DIGITAL
VARIABLE GAIN AMPLIFIER, 30 -400 MHz Typical Applications Features The HMC680LP4(E) is ideal for: TTL/CMOS compatible parallel or latched
parallel control interface • Cellular/3G Infrastructure High Output IP3: +40 dBm (At all gain settings) • WiBro / WiMAX / 4G Low Noise Figure: 5 dB • Microwave Radio & VSAT Wide Gain Control Range: 23 dB • Test Equipment and Sensors 24 Lead 4x4 mm SMT Package: 16 mm2 • IF & RF Applications Excellent State & Step Accuracy (±0.05 dB) General Description Functional Diagram The HMC680LP4(E) is a digitally controlled variable
gain amplifier which operates from 30 to 400 MHz,
and can be programmed to provide -4 dB to +19 dB
of gain, in 1 dB steps. The HMC680LP4(E) delivers
noise figure of 5 dB in its maximum gain state, with
output IP3 of up to +40 dBm in any state. This high
linearity DVGA also provides a differential RF output
which can be used to interface directly with SAW
filters in Tx and Rx applications, and with digital to
analog converters in Rx chains. The HMC680LP4(E)
is housed in a RoHS compliant 4x4 mm QFN leadless
package, and is CMOS/ TTL compatible. Variable gain amplifiers -digital -SMT 12 12 -1 Electrical Specifications, TA = +25° C, 50 Ohm System, Vdd = +5V
