Agilent HSMS-285x series zero bias Schottky detector diodes are designed and optimized for use in small signal (Pin <-20 dBm) applications at frequencies below 1.5 GHz. They are ideal for RF/ID and RF Tag applications where primary (DC bias) power is not available.
The HSMS-285x family of zero‑bias Schottky detector diodes is designed for small‑signal applications (P< ‑20 dBm) at frequencies below 1.5 GHz, ideal for RF/ID and RF tag use where no DC bias is available. The series offers matched diode pairs, low flicker noise, and high detection sensitivity.
Available in SOT‑23, SOT‑143, SOT‑323 and SOT‑363 surface‑mount packages, the datasheet provides electrical specifications (reverse voltage, forward voltage, capacitance), typical parameters, equivalent circuit models, and guidance on detector circuit design, noise performance, and assembly instructions.
