Description
Features
The B-8250 line of zero bias Schottky detector diodes by • Surface Mount SOT-23 3 Pin Packages
Bay Linear have been engineered for use in small signal • SOT-143 Packages 4 Pin Packages
(Pin<-20 dBm) applications at frequencies below 2.0 • Miniature SOT-323/363 3 pin and 6 pin
GHz. The ideal applications are for RF/ID and RF Tags • High Detection Sensitivity:
where primary (DC bias) power is not available.
up to 50mV/µW at 915 MHz
• Low Flicker Noise: -165 dBV/Hz at 100Hz
At Bay Linear, our commitment to quality components • Low reverse leakage
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
• •
Matched Diodes High Thermal Conductivity for greater Power
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.
