PRODUCT OVERVIEW

This is a small band pass filter centered at 3.45 GHz with a bandwidth of 100 MHz. The band extends from 3400 MHz to 3500 MHz.

Typical insertion loss of less than 4 dB in the pass band. This filter has excellent rejection specifications, provides power handling of up to a maximum +20 dBm and has an operating temperature range of -40C to +85C.
 

APPLICATIONS

The frequency range from 3400 to 3500 MHz is part of 5G Band n78 and 4G LTE band 42. 

Internationally, this range is considered part of the broader C-Band, which typically spans from 3.4 GHz to 4.2 GHz. The 3.4–3.6 GHz segment is especially important for 5G and advanced wireless services

This band is used for:

• 5G Mobile Networks
• CBRS
• Fixed Wireless Access
• Radiolocation and Defense (3400–3475 MHz) 
• Radar Systems
• Satellite Services

The filter can be used in radio scanners, receivers, spectrum analyzers and other radio apparatus.
