It consists of a high impedance differential input stage, a low impedance differential output stage, and a differential gain-controlled amplifier. The voltage gain may be varied by applying an analog control voltage. The device is fabricated on an advanced Bi-CMOS process, and is housed in an eight-lead SOT23 package. 2.80 3.00 0.650 2.60 3.00 3°MAX 0°MIN 1.44 1.04 0.127 *When Pin 1 is in upper left, text reads downward (as shown). 0.35 0.55 Optimum Technology Matching® Applied Package Style: SOT23-8 üSi Bi-CMOS Si BJT GaAs HBT SiGe HBT GaAs MESFET Si CMOS Features Single 5V Positive Power Supply 26dB Gain Range 150MHz Bandwidth VCC 1 GND 2 VOUT 3 VOUTB 4 Biasing & AGC Control 8 VCC 7 VIN 6 VINB 5 VAGC Compact Package Ordering Information RF3330 RF3330 PCBA RF3330 PCBA IF Gain Controlled Amplifier Fully Assembled Evaluation Board - 75 Ω Fully Assembled Evaluation Board - 50 Ω Tel (336) 664 1233 Fax (336) 664 0454 http://www.rfmd.com Functional Block Diagram RF Micro Devices, Inc. 7628 Thorndike Road Greensboro, NC 27409, USA Rev A2 010820 3-1 LINEAR CATV AMPLIFIERS Product Description TEXT* RF3330 Absolute Maximum Ratings Parameter Supply Voltage Operating Ambient Temperature Storag...
