HMC680LP4E

HMC680LP4 / 680LP4E v03.0609 BiCMOS MMIC 5-BIT DIGITAL VARIABLE GAIN AMPLIFIER, 30 - 400 MHz Typical Applications The HMC680LP4(E) is ideal for: • Cellular/3G Infrastructure • WiBro / WiMAX / 4G • Microwave Radio & VSAT • Test Equipment and Sensors • IF & RF Applications Features TTL/CMOS compatible parallel or latched parallel control interface High Output IP3: +40 dBm (At all gain settings) Low Noise Figure: 5 dB Wide Gain Control Range: 23 dB 24 Lead 4x4 mm SMT Package: 16 mm2 Excellent State & Step Accuracy (±0.05 dB) Functional Diagram General Description 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. 13 VARIABLE GAIN AMPLIFIERS - DIGITAL - SMT Electrical Specifi cations, TA = +25° C, 50 Ohm System, Vdd = +5V Parameter Frequency Range Gain (Maximum Gain State) Gain Control Range Input Return Loss Output Return Loss Gain Accuracy: (Referenced to Maximum Gain State) All Gain States Output Power for 1dB Compression Output Third Order Intercept Point (Two-Tone Output Power= +5 dBm Each Tone) [1] Output Second Order Intercept Point (Two-Tone Output Power= +5 dBm Each Tone) [1] Harmonics Step Accuracy (Referenced to Maximum Gain State) Noise Figure (max gain state) Switching Characteristics Control Supply Current Idd Amp Supply Current (RFOUTP) Amp Supply Current (RFOUTN) [1] Test frequency 50 MHz tRise, tFall (10/90% RF) tON, tOFF (50% CTL to 10/90% RF) 2nd Order 3rd Order 17 Min.
