SURFACE MOUNT–CERAMIC
ATTENUATOR, PIN DIODE
MODEL PI-810
150–2000 MHz
FEATURES
• PCS Frequency Coverage: 150-2000 MHz
• Balanced 4 Diode Configuration Increases Attenuation and
Doubles Upper Frequency Limit
• Low VSWR and Flat Attenuation Characteristics
• Silicon PIN Diodes on Ceramic Offer Improved Insertion Loss
Compared to GaAs
• Superior Intermodulation Distortion Characteristics
• Inherently Compensates for VSWR and Temperture Variations
• Rugged Alumina “Surfpac” Package Ideal for Surface Mount
Applications
• Can be Optimized Over Lower Fequency Ranges by Changing
Capacitor Values
• BEST CHOICE for PCS and GSM Applications
• Lower Cost Alternative to PI-820 Version
