Active Spectrum has introduced low-loss, tunable filter modules in the 225 to 6000 MHz bands, using a proprietary tunable resonator to implement a filter with wideband tuning, low insertion loss (1.0 dB typical) and high RF power handling capability (> 20 W). The tunable filters show significantly improved insertion loss, linearity and static power consumption compared to conventional varactor or PIN diode tuned filter modules. These miniature tunable filters show industry leading performance in terms of low insertion loss, high RF power handling capability and very wide tuning range (octave plus).
These products are ideal solutions for difficult co-site interference problems in next generation communication systems for commercial and military applications. Active Spectrum offers standard tunable filter models covering the frequency bands from 700 MHz to 4 GHz, and custom designs up to 18 GHz.
