Microwave Absorber Board Level Shield

Laird Technologies Microwave Absorber Board Level Shields (ABLS) technology for EMI shielding solutions utilizes a combination of QZorb RFSW surface wave absorbers and board level shields to create a product design to meet specific application requirements.
Q-Zorb RFSW surface wave absorbers are thin, magnetically loaded elastomeric sheets designed to provide emi protection at high angles of incidence for surface wave attenuation.

FEATUREs and Benefits:
• ABLS has enhanced shielding effectiveness at frequencies from 1 – 40 Ghz
• Use inside of microwave housings to reduce internal resonance and lower the "Q" of the microwave cavity
• Minimizes crosstalk and susceptibility without impacting system speed
• Effective in isolating antennas from ground plane reflections
• Custom shapes and other material options are available
• Provides isolation of board level components
• Low height down to 0.04” (1,0mm) to accommodate mother/daughter board configurations
• Secure cover design is ideal for applications that could be subject to shock and vibration

APPLICATIONs
• Any application requiring board level shielding
• Wireless handsets, PC cards
• High frequency communications equipment, basestations
• PDAs
• Desktop and laptop computers
• Portable and non-portable electronic devices
