| HMC972LP5E v00.1210 GaAs MMIC ANALOG VARIABLE GAIN AMPLIFIER, 0.5 - 6.0 GHz Features Wide gain Control range: -35 to +15 db High Output ip3: +28 dbm positive analog Control: 0 to +5V Can be configured with 1 or 2 attenuators 32 lead 5x5 mm smT package: 25 mm2 Typical Applications The HMC972LP5E is ideal for: * Cellular/3g infrastructure * Wibro / WimaX / 4g * microwave radio & VsaT * Test equipment and sensors * if & rf applications Functional Diagram General Description The HMC972LP5E is an analog controlled variable gain amplifier composed of two identical voltage variable attenuators in combination with an ingap HbT gain block mmiC amplifier which operates from 0.5 to 6 gHz, and can be controlled to provide anywhere from 15 db of gain to 35 db of attenuation. The HMC972LP5E delivers noise figure of 7.5 db in its maximum gain state, with output ip3 of up to +28 dbm. The HMC972LP5E is housed in a roHs compliant 5x5 mm Qfn leadless package, and requires no external matching components. 13 Variable gain amplifiers - analOg - smT Electrical Specifications, TA = +25 C, 50 Ohm System, Vdd = ATT1Vdd = ATT2Vdd = +5V [1] parameter insertion gain (Vctl = 0V) frequency 0.5 - 2.7 gHz 2.7 - 4.0 gHz 4.0 - 6.0 gHz 0.5 - 4.0 gHz 4.0 - 6.0 gHz min. 10.5 6 Typ. 13 9 0 50 42 12 10 0.5 - 2.7 gHz 2.7 - 4.0 gHz 4.0 - 6.0 gHz 0.5 - 2.7 gHz 2.7 - 4.0 gHz 4.0 - 6.0 gHz 16 13 6 29 26 20 7.5 75 85 0.2 0.2 102 0.3 0.3 max.
