1 / 55 page  Data Sheet ADMV8809 0.5GHz to 9GHz, Digitally Tunable, High-Pass Filters and Low-Pass Filters Rev. A DOCUMENT FEEDBACK TECHNICAL SUPPORT One Analog Way, Wilmington, MA 01887-2356, U.S.A. | Tel: 781.935.5565 | ©2025 Analog Devices, Inc. All rights reserved. FEATURES ► Digitally tunable, high-pass and low-pass tuning ► Suboctave bandwidths with additional user adjustability ► Rejection: 40dB ► Single-chip replacement for discrete filter banks ► Compact, 8mm × 8mm × 1.07mm LGA package APPLICATIONS ► Land mobile radios ► Test and measurement equipment ► Military radars, electronic warfare, and electronic countermeas- ures ► Satellite communications ► Industrial and medical equipment GENERAL DESCRIPTION The ADMV8809 is a fully monolithic microwave IC (MMIC) that features digitally selectable operating frequencies. The device fea- tures four independently controlled high-pass filters (HPFs) and low-pass filters (LPFs) that span the 0.5GHz to 9GHz frequency range (fCENTER). The flexible architecture of the ADMV8809 allows the 3dB cutoff frequency (f3dB) of the high-pass and low-pass filters to be control- led independently. The digital logic control on each filter is 3-bits wide (eight states) and controls the on-chip reactive elements to adjust the f3dB. The typical insertion loss is <6.2dB. When using the HPF = LPF state, the filter has 40dB rejection for the low side at 0.5 × fU3dB and for the high side at 2 × fL3dB, which is ideally suited for minimizing system second-order intercept (IP2) and harmonics. This tunable filter can be used as a smaller alternative to large switched filter banks and discrete component-based tunable filters, and the ADMV8809 provides a dynamically adjustable solution in advanced communications applications.
