This data sheet introduces the Agilent HSMS-285x family of zero bias Schottky detector diodes. These diodes are ideal for small signal applications (Pin <-20 dBm) 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 are surface‑mount Schottky detector diodes optimized for small‑signal applications (Pin < ‑20 dBm) at frequencies below 1.5 GHz. They are intended for RF/ID and RF tag designs where no DC bias is available, offering high detection sensitivity and low flicker noise.
The document provides detailed electrical specifications, absolute maximum ratings, typical performance curves, recommended PCB footprints, and assembly guidelines. It also includes ordering information for various package types (SOT‑23, SOT‑143, SOT‑323, SOT‑363) and lead‑free options. This manual is written in Chinese.
| Detection Sensitivity | up to 50 mV/µW at 915 MHz |
|---|---|
| Flicker Noise | -162 dBV/Hz at 100 Hz |
| Peak Inverse Voltage (PIV) | 2.0 V |
| Junction Temperature (TJ) | 150 °C |
| Storage Temperature Range | -65 °C to 150 °C |
| Operating Temperature Range | -65 °C to 150 °C |
For input powers greater than –20 dBm, use the HSMS‑282x series below 4 GHz or the HSMS‑286x series above 4 GHz.
The HSMS‑285x diodes are offered in SOT‑23, SOT‑143, SOT‑323 and SOT‑363 surface‑mount packages.
Typical detection sensitivity is up to 50 mV per microwatt at 915 MHz.
The reflow peak temperature should not exceed 235 °C.
