Tunable Filters Screen 0.1 to 3.0 GHz

July 10, 2014

Lines of mechanically tuned bandpass and band-reject filters are designed for applications to 3 GHz.

Lines of tunable band-stop and bandpass filters have been developed for test and other applications from 100 MHz to 3 GHz. A total of six bandpass filters offer octave-band tuning from 125 MHz to 3 GHz and 5% pass bands. These five-section mechanical designs achieve mechanical dial accuracy within 1%. Five new band-reject filters range from 100 MHz to 2 GHz with 1% rejection bandwidths.

These three-section designs boast mechanical dial tuner accuracy to 0.5%. These durable, silver-plated filters, which are capable of more than 50-dB attenuation, are supplied with Type-N connectors. Each is rated for 50 W CW RF/microwave power.
