13 8 14 7 15 6 16 5 QPC4043 75 5 3000MHz Voltage Controlled Attenuator Product Overview QPC4043 is a fully monolithic voltage-controlled attenuator (VCA) that provides over 25dB of gain control range over a frequency range of 5MHz to 3000MHz. The QPC4043 employees a closed loop design that provides a more controlled attenuation response over frequency and 16 Pin 3x3mm Laminate (LGA) Package temperature conditions. This attenuator is matched to 75 over its control range and frequency with no external matching components required. The QPC4043 is available in a space saving 16-pin 3 x 3mm Laminate (LGA) package Key Features with minimal external components. Patented Circuit Architecture Over 25dB of attenuation range Frequency range of 5MHz to 3000MHz Functional Block Diagram Low insertion loss of 1.2dB at 1200MHz Operates over wide supply voltage range of 3V to 5.5V Supply current: 5mA (typical) Excellent distortion characteristics with IIP3 > 45dBm Linear in dB control characteristic 1 12 GND GND High 1dB Compression Point >+30dBm CONTROL BLOCK GND 2 11 GND Applications RFIN 3 10 RFOUT DOCSIS 4.0 Equalizer Circuits ATTEN DOCSIS 4.0 Attenuator GND 4 9 GND DOCSIS 4.0 Amplifier and Nodes Cable Modems CATV/DOCSIS Amps and Nodes High Linearity Power Control RPHY and RPHY Shelf applications Top View Ordering Information Part No. Description QPC4043SB Sample Bag with 5 Pieces QPC4043SR 7 Reel with 100 Pieces QPC4043TR7 7 Reel with 2500 Pieces QPC4043EVB-01 5 3000MHz PCBA Data Sheet Rev.
