This version: Jul. 1998 Previous version: Jan. 1998 E2Q0021-38-72 ¡ electronic components KGF1181B ¡ electronic components KGF1181B Medium-Power Amplifier GENERAL DESCRIPTION The KGF1181B is a two-stage medium-power UHF-band amplifier that features high gain, high output power, and low power operation. The internally matched 50 W input and output eliminate external impedance-matching circuits. All specifications for this device are guaranteed at 5 V and 850 MHz. Because of the high gain and high output power, the KGF1181B is ideal as a transmitter-intermediate-stage amplifier for personal handy phones. FEATURES • Internally matched 50 W input and output • High linear gain: 20 dB (min.) • High output power: 11.5 dBm (min.) • Low current operation: 40 mA (max.) • Self-bias circuit configuration with built-in source capacitor • Package: 4PSOP PACKAGE DIMENSIONS 1.8±0.1 0.85±0.05 0.36 0.74 0.3 MIN 1.1±0.15 0.4 +0.1 –0.05 1.5±0.15 3.0±0.2 0.6 +0.1 –0.05 0 to 0.15 Package material 1.9±0.1 Lead frame material 0.125 +0.03 –0 2.8±0.15 Epoxy resin Pin treatment 42 alloy Solder plating Solder plate thickness 5 mm or more (Unit: mm) 1/8 ¡ electronic components KGF1181B MARKING (4) (3) C X X (1) (2) NUMERICAL LOT NUMBER NUMERICAL PRODUCT TYPE (1) IN (2) VD1 (3) OUT (4) GND CIRCUIT VD1(2) Cf CC OUT(3) Rf IN(1) Q1 Q2 RS1 RG1 CS1 RG2 RS2 CS2 GND(4) 2/8 ¡ electronic components KGF1181B ABSOLUTE MAXIMUM RATINGS Item Supply voltage Symbol Conditions Unit Min.
