Digitally Tunable, High-Pass And Low-Pass Filter: ADMV8913

ADMV8913_CC-30-4

The ADMV8913 is a fully monolithic microwave integrated circuit that that features a digitally selectable frequency of operation. The device has an integrated high-pass filter and an integrated low-pass filter, that allow a pass-band response within the 7 to 12 GHz frequency range.

The flexible architecture of the ADMV8913 allows for 3 dB cutoff frequency (f3dB) of the high-pass and the low-pass filter to be controlled independently. The digital logic control on each filter is 4 bits wide (16 states) and controls the on-chip reactive elements to adjust the f3dB. The typical insertion loss is 5 dB, and the wideband rejection is 35 dB, which is ideally suitable for minimizing system harmonics.

This tunable filter can be used as a smaller alternative to large switched filter banks and cavity tuned filters, and this device provides a dynamically adjustable solution in advanced communications applications.

Additional Product Features Include:

  • Digitally tunable, lower and upper 3dB cutoff frequencies
  • Optimal wideband rejection: 35 dB
  • Single chip replacement for discrete filter banks
  • Compact 6 × 3 x 0.89 mm LGA package
