626LP5E

HMC626LP5 / 626LP5E v06.0709 0.5 dB LSB GaAs MMIC 6-BIT DIGITAL VARIABLE GAIN AMPLIFIER, DC - 1 GHz Typical Applications The HMC626LP5(E) is ideal for: • IF & RF Applications • Cellular/3G Infrastructure • WiBro / WiMAX / 4G • Microwave Radio & VSAT • Test Equipment and Sensors Features +8.5 dB to +40 dB Gain Control in 0.5 dB Steps High Output IP3: +36 dBm ±0.25 dB Typical Gain Step Error Single +5V Supply 32 Lead 5x5mm SMT Package: 25mm2 Functional Diagram General Description The HMC626LP5(E) is a digitally controlled variable gain amplifier which operates from DC to 1 GHz, and can be programmed to provide anywhere from 8.5 dB, to 40 dB of gain, in 0.5 dB steps. The HMC626LP5(E) delivers noise figure of 2.8 dB in its maximum gain state, with output IP3 of up to +36 dBm in any state. This single positive control line per bit digital VGA incorporates off chip AC ground capacitors for near DC operation, making it suitable for a wide variety of RF and IF applications. The HMC626LP5(E) is housed in a RoHS compliant 5x5 mm QFN leadless package, and requires no external matching components. A serial control version of this product is available as the HMC681LP5(E). 13 VARIABLE GAIN AMPLIFIERS - DIGITAL - SMT Electrical Specifi cations, TA = +25° C, Vdd = Vs= +5V, Vctl= 0/ +5V Parameter Gain (Maximum Gain State) Gain Control Range Input Return Loss Output Return Loss Gain Setting Accuracy: (Referenced to Maximum Gain State) All Gain States Output Power for 1 dB Compression Output Third Order Intercept Point (Two-Tone Output Power= 5 dBm Each Tone) Noise Figure Switching Characteristics tRISE, tFALL (10/90% RF) tON, tOFF (50% CTL to 10/90% RF) Total Supply Current DC - 1.0 GHz 130 140 176 225 ns ns mA 0.5 - 1.0 GHz DC - 1.0 GHz DC - 1.0 GHz DC - 1.0 GHz Frequency DC - 0.5 GHz 0.5 - 1.0 GHz Min. 37 30 Typ. 42.5 35.0 31.5 20 15 ± (0.15 + 3% of Relative Gain Setting) Max. 20 36 2.8 Max.
