AM3275

The AM3275 from Mercury Systems is a Digitally Tunable Bandpass Filter Bank with passbands spanning 5.5 to 11.5 GHz, 9 to 14.5 GHz, 11.5 to 16.5 GHz, and 13.5 to 18 GHz. It is a low-loss filter solution designed for SWaP-constrained applications. This filter incorporates four separate tunable filters, with each having four states. It has a passband insertion loss of 6 dB and provides an out-of-band rejection of 40 dB. This tunable filter also includes an additional 10 GHz bypass path to support extension for operation at low frequencies. 

The AM3275 comes with an evaluation board having SMA connectors and a DIP switch for controlling the filter setting, allowing for customization of the filter bank. This bandpass filter bank requires a DC supply of 3 to 5.2 V and consumes 7 mA of current. It is available in a QFN package that measures 5 x 5 mm.
