What made you select Nuvotronics’ PSF19B03S K-Band Bandpass Filter?
I selected the Nuvotronics PSF19B03S K-band bandpass filter because it offers excellent low-loss performance and high rejection in a space-saving surface-mount form factor. When designing RF front ends for satellite communications, engineers need filters that combine sharp roll-off, minimal signal loss, and easy integration. As systems become more densely packed and performance requirements tighten, finding a filter that delivers both electrical precision and mechanical simplicity becomes a key design priority.
The PSF19B03S leverages Nuvotronics’ proprietary PolyStrata® microfabrication process to deliver high performance in a compact 8.44 x 4.63 x 1.1 mm footprint. With a passband from 17.7 to 21.2 GHz and typical insertion loss of less than 1 dB, this surface-mount interdigital filter enables clean signal transmission while conserving board space and power budget.
The “Polystrata” microfabrication process is highly repeatable meaning that device to device variation is inherently low, making them ideal for use in multi antenna arrays.
The PSF19B03S has excellent rejection between 27.5 GHz and 31 GHz, ensuring high isolation between Uplink and downlink frequencies
The Polystrata robust mechanical structure make it ideal for demanding applications in both space and terrestrial environments. Compatibility with standard SMT processes also simplifies assembly and supports high-volume production.
