With control over a +30 dB (max.) to –50 dB (min.) range at 130 MHz, the device also provides excellent gain slope linearity. The KGF2441 operates with a single 5-V power supply with a low current operation of 5 mA (typ.) The device is particularly suited to IF-stage amplifier applications, such as portable handy phones based on CDMA-type digital cellular technology operating over wide dynamic ranges. FEATURES • Wide dynamic range: 80 dB (min.) • Excellent gain slope linearity for AGC voltage • Low current operation: 5 V, 5 mA (typ.) • Package: 8PSOP PACKAGE DIMENSIONS 5.2±0.2 1.6±0.2 0.15±0.1 0 to 0.3 5.0±0.2 6.8±0.4 0.40MIN Package material 0.35±0.1 1.27±0.2 Lead frame material Pin treatment Solder plate thickness INDEX MARK Epoxy resin 42 alloy Solder plating 5 mm or more (Unit: mm) 1/5 ¡ electronic components KGF2441 MARKING (8) (7) (6) (5) K2441 ¡ XXX INDEX (1) (2) (3) (4) PRODUCT TYPE COMPANY LOGO LOT NUMBER (1) VOUT (2) VDD3 (3) VDD2 (4) VDD1 (5) VIN (6) GND (7) VAGC (8) GND CIRCUIT 2/5 ¡ electronic components KGF2441 ABSOLUTE MAXIMUM RATINGS Item Supply voltage 1 Supply voltage 2 Supply voltage 3 Gain control voltage Input voltage Output voltage Total power dissipation Storage temperature Symbol VDD1 VDD2 VDD3 VAGC VIN VOUT Ptot Tstg Condition Ta = 25°C Ta = 25°C Ta = 25°C Ta = 25°C Ta = 25°C Ta = 25°C Ta = 25°C — Unit V V V V V V mW °C Min. — — — 0 –3 VDD/2–0.4 — –45 Max. 5.5 5.5 5.5 VDD–2 0.4 VDD/2+3 or VDD 200 125 ELECTRICAL CHARACTERISTICS Ta = 25°C , f = 130 MHz , VDD = 5 V Item Maximum gain Minimum gain Output IP3 Noise figure Supply current Input impedance Output impedance Symbol GMAX GMIN IP3 F |DD ZIN ZOUT Condition VAGC = 0 V VAGC = 5 V VAGC = 0 V, fLO =129 MHz VAGC = 0 V VAGC = 0 V VAGC = 0 V VAGC = 0 V Unit dB dB dBm dB mA W W Min. 30 — — — — 800 — Typ. — — –4.5 — 5 — 175 Max. — –50 — 10 10 1200 — 3/5 ¡ electronic components KGF2441 RF CHARACTERISTICS 4/5 ¡ electronic components KGF2441 Test Circuit for KGF2441 at 130 MHz VDD 39W C1 0.01mF C2 0.01mF 39W C3 0.01mF 39W r e w 0.1mH 7pF 0.01mF t RF IN 0.15mH KGF2441 y u 78W VAGC q 1000pF 0.22mH 14pF RF OUT i 5/5 E2Y0002-29-11 NOTICE 1.
