HMC997LC4

HMC997LC4 v00.0511 Variable Gain amplifier 17 to 27 GHz 0 Variable Gain amplifier - SmT Typical applications The HmC997lC4 is ideal for: • Point-to-Point Radio • Point-to-Multi-Point Radio • EW & ECM Subsystems • Ka-Band Radar • Test Equipment features Wide Gain Control range: 15 db Single Control Voltage Output ip3 @ max Gain: +31 dbm Output p1db: +24 dbm no external matching 24 lead 4x4 mm SmT package: 16 mm2 functional Diagram General Description The HmC997lC4 is a Gaas mmiC pHemT analog variable gain amplifier and / or driver amplifier which operates between 17 and 27 GHz. ideal for microwave radio applications, the amplifier provides up to 20.5 db of gain, output p1db of up to +24 dbm, and up to +31 dbm of output ip3 at maximum gain, while requiring only 170 ma from a +5V supply. a gain control voltage (Vctrl) is provided to allow variable gain control up to 15 db. Gain flatness is excellent making the HmC997lC4 ideal for eW, eCm and radar applications. The HmC997lC4 is housed in a roHS compliant 4 x 4 mm ceramic Qfn leadless package and is compatible with high volume surface mount manufacturing. electrical Specifications, Ta = +25°C, Vdd1, 2, 3 = 5V, Vctrl= -4.5V, idd = 170 ma* parameter frequency range Gain Gain flatness Gain Variation Over Temperature Gain Control range noise figure input return loss Output return loss Output power for 1 db Compression (p1db) Saturated Output power (psat) Output Third Order intercept (ip3) Total Supply Current (idd) 21 12 17.0 min.
