| MA4P274-1225 Quad PIN Diode Attenuator 10 - 4000 MHz Features * 4 PIN diodes in a SOT-25 Plastic Package * Externally Selectable Bias and RF Matching Network * 10 - 4,000 MHz Useable Frequency Band * + 43 dBm IP3 @ 1000 MHz (50 ) * 1.0 dB Loss @ 1000 MHz (50 ) * 30 dB Attenuation @ 1000 MHz (50 ) M/A-COM Products Rev. V2 Functional Schematic Description M/A-COM's MA4P274-1225 is a wideband, lower insertion loss, high IP3, Quad PIN Diode Attenuator in a low-cost, surface mount SOT-25 package. Four PIN Diodes in one package reduce design parasitics and improve circuit density. These PIN Diode Attenuators perform well where RF Signal Amplitude Control is required in 50 Handset Circuits and 75 Broadband CATV Systems. Exceptional Insertion Loss, Attenuation Range, and IP3 at <10 mA bias make these devices suitable for better power level control in RF Amplifiers.
