BAW Filter Modules for Defense and Aerospace

Qorvo has unveiled two S-Band switched filter bank modules, the QPB1034 and QPB1036, tailored for defense and aerospace radar applications necessitating frequency agility and spectral control. These modules integrate BAW filtering technology and swift-switching logic in compact 6.0 x 6.0 mm packages, catering to size limitations in multi-function radar platforms.

The QPB1034 functions within the 2.7-3.1 GHz frequency range, encompassing four filters plus one bypass path. It boasts a 480-nanosecond switching speed with 45 dBc out-of-band rejection at 50 MHz from the band edge. The insertion loss is typically measured at 3.5 dB across the operating bandwidth.

On the other hand, the QPB1036 spans the 2.9-3.5 GHz frequency range and integrates six filters plus one bypass path, offering enhanced channel density compared to the QPB1034. Despite the increased filters, this module maintains the same 480 nanosecond switching speed and 45 dBc out-of-band rejection, with insertion loss remaining at 3.5 dB typical throughout the frequency range.

Both modules leverage BAW filter technology alongside silicon-on-insulator switch architecture, enabling rapid frequency tuning and signal control functionalities crucial in agile radar front-end systems. The compact form factor reduces board space requirements while upholding filtering performance characteristics.

These modules are targeted towards S-Band radar systems across land, sea, and airborne platforms where swift frequency switching and precise spectral control are imperative. The BAW technology offers rejection characteristics and channel selectivity suitable for applications requiring multiple frequency bands within compact system architectures.
