What circuit boards do we do? (37) AD300D High Frequency PCB

Introduction

AD300D laminates are ceramic-filled, glass-reinforced PTFE-based materials designed to offer a controlled dielectric constant, low loss performance, and excellent passive intermodulation (PIM) performance. They are specifically engineered and manufactured to meet the demands of today’s wireless antenna markets.This PTFE resin based material is compatible with standard PTFE fabrication and provides a cost-effective construction to improve electrical and mechanical performance.

Features

The AD300D laminates demonstrate an outstanding passive intermodulation (PIM) value of -159 dBc at 30 mil and -163 dBc at 60 mil, measured with reflected 43 dBm swept tones at 1900 MHz. This low PIM performance enhances antenna efficiency and reduces yield loss due to PIM-related issues.

AD300D features controlled dielectric constant of 2.94 at 10 GHz, and low dissipation factor of 0.0021 at 10 GHz, 23°C, and 50% relative humidity.

Additionally, the thermal coefficient of the dielectric constant is measured at -73 ppm/°C across a temperature range of 0-100°C at 10 GHz, underscoring its stability under varying thermal conditions.

Boasting remarkable thermal resilience, AD300D surpasses a decomposition temperature (Td) exceeding 500°C.

Its coefficient of thermal expansion stands at 24 ppm/°C in the X-axis, 23 ppm/°C in the Y-axis, and 98 ppm/°C in the Z-axis within a temperature range of -55 to 288°C.

Furthermore, AD300D offers robust adhesion and durability, showcasing over 60 minutes of resistance to delamination at 288°C.

The material's moisture absorption rate is minimal, at just 0.04% under E1/105 + D48/50 conditions.
