The ATEK888BP5 from ATEK MIDAS is a Digitally Tunable MMIC Low-Pass Filter that operates from 20 to 550 MHz. It is designed to provide low in-band loss and high out-of-band rejection. This 50-ohm GaAs MMIC filter has an insertion loss of 2 dB and provides an out-of-band rejection of -45 dBc. It has an input IP3 of +43 dBm and input/output return losses of 13 dB. This digitally tunable filter supports 32 selectable frequency bands through a 5-bit GPIO control interface, with switching times of 500 ns (on) and 650 ns (off).
The ATEK888BP5 requires a 3 to 5.5 V DC supply and draws 5 mA of current. It is available in a 5 × 5 mm QFN surface-mount package and operates over a temperature range of -40°C to +85°C. This filter is ideal for wideband receivers, telecommunications, test and measurement, SATCOM, and SDR applications.
