Low-loss bandpass RF filter using MEMS capacitance switches to achieve a one-octave tuning range and independently variable bandwidth

We demonstrate a low insertion loss (1.5dB) tunable two-pole bandpass radio frequency filter with a tuning range of one octave (812-1752 MHz). It is also tunable in band width, with 3dB-bandwidths of 7 to 42% being achieved. The circuit used consists of two fixed high quality factor toroidal inducto...
