Description
AI
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.ApplicationsTest and measurement equipmentMilitary radar and electronic warfare/electronic countermeasuresSatellite communicationsIndustrial and medical equipment
