Evaluating Avago's HMPP-3860 and HMPP-3890 PIN Switches on the RW053B Demoboard-App Note

From Avago Technologies
 

 
Avago Technogies' HMPP-3860 and HMPP-3890 are part of an extensive family of PIN diodes in the ultra-miniature Minipak package. This lead-less package offers reduced parasitics when compared to conventional leaded parts. Additionally, the better thermal conductivity of the Minipak over conventional leaded packages allows higher power to be dissipated safely. The HMPP-3860 is best suited to switching applications where low capacitance at zero bias is the primary consideration, whereas the HMPP-3890 is optimized for switching at low current. The series switch configuration is useable until 3 GHz. Above this frequency limit, better isolation can be achieved through a combination of shunt switching and quarter wavelength transmission line.
Products & Services
PIN diodes are three-layer semiconductor diodes consisting of an intrinsic layer separating heavily doped P and N layers. The charge stored in the intrinsic layer in conjunction with other diode parameters determines the resistance of the diode at RF and microwave frequencies.

Schottky diodes in their simplest form consist of a metal layer that contacts a semiconductor element. The metal / semiconductor junctions exhibit rectifying behavior (i.e., the current passes through the structure more readily with one polarity than the other).

Diode arrays are composed of multiple discrete (usually unconnected) diodes on a single silicon chip. Diode arrays are important semiconductor products because they save assembly time and improve reliability over individually packaged diodes. In general, diode arrays use four or more diodes in a single package. Search by Specification | Learn more about Diode Arrays
RF diodes are designed to handle high-power radio frequency (RF) signals in stereo amplifiers, radio transmitters, television monitors, and other RF or microwave devices. Search by Specification | Learn more about RF Diodes
Power diodes are used mainly in high-power applications. They are built with large P-N junctions in order to pass large amounts of current and dissipate large amounts of heat. Search by Specification | Learn more about Power Diodes
