Description

The B-8250 line of zero bias Schottky detector diodes by Bay Linear have been engineered for use in small signal (Pin<-20 dBm) applications at frequencies below 2.0 GHz. The ideal applications are for RF/ID and RF Tags where primary (DC bias) power is not available.

At Bay Linear, our commitment to quality components gives our customers a reliable second source of products, which are tested at a more stringent level than our competitors. Manufacturing techniques assure that when two diodes are mounted into a single package they are taken from adjacent sites on the wafer.

In cross referenced parts, we guarantee pin to pin compatibility. The various package configurations available provide a low cost solution to a wide variety of design problems.

Features

• Surface Mount SOT-23 3 Pin Packages

• SOT-143 Packages 4 Pin Packages

• Miniature SOT-323/363 3 pin and 6 pin

• High Detection Sensitivity:

up to 50mV/µW at 915 MHz

• Low Flicker Noise: -165 dBV/Hz at 100Hz

• Low reverse leakage

• Matched Diodes

• High Thermal Conductivity for greater Power
