HSMP-3866 Quad PIN Diode Pi Attenuator 300 kHz to 3 GHz in SOT 25 Package Data Sheet Description Features Avago Technology’s HSMP-3866 is a wideband, low insertion loss, low current, Quad PIN Diode Pi Attenuator in a low cost surface mount SOT-25 package. It provides a good match and flat attenuation over an extremely wide band from 300 kHz to 3 GHz. • 4 PIN Diodes in a SOT-25 package The SOT-25 packages gives a reduction in part count and takes up less space on board compared to multi package solutions. • MSL-1 and Lead-free Four PIN Diodes in one package encourages performance repeatability for improved production yield at board level. Package Marking and Pin connections 3 2 • 300 kHz to 3 GHz usable frequency band • Low Current • Low insertion Loss • Tape & Reel packaging option available Specification At 1 GHz, V+=1.2V • IIP3 = 30 dBm (Typical) • Attenuation = 36 dB (Typical) • Insertion Loss = -2.5 dB (Typical) • Return Loss = -18 dB (Typical) 1 Application Note: Package marking provides orientation and identification “BT”= Device Code “x” = Month code indicates the month of manufacture BTx 5 4 Pin 3 : RF In/Out Pin 4 : Shunt Bias Pin 2 : Series Bias Pin 1 : RF In/Out Pin 5 : Shunt Bias • Broadband system application (i.e., CATV, WCDMA, etc) • General purpose Voltage-Control-Attenuator for low current applications.
