Overview
The Ranatec RI 260 is a high performance electronically tunable band reject filter (notch filter) using state-of-the-art technology. RI 260 is divided into filter segments corresponding to existing cellular mobile phone bands: 455, 698 – 1000, 1400 – 2000, 2000 – 2700, and 3400-3800  MHz. Filter characteristics are remained constant across each band. This is achieved by ingenious microwave design, digital signal processing and the use of state-of-the-art components.
A frequency extension option for conformance testing up to 26.5 GHz is available. It contains highpass and lowpass filters in a special configuration for coexistence with RI 260.

Applications
The RI 260 Tunable Notch Filter is designed for applications such as:
• Conformance testing according to TS 136 521-1
• Spurious emissions measurements
• Blocking measurements
• Design verification of radio transmitters and receivers
