Overview

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

The ADMV8809 is a fully monolithic microwave IC (MMIC) that features digitally selectable operating frequencies. The device features four independently controlled high-pass filters (HPFs) and low-pass filters (LPFs) that span the 0.5GHz to 9GHz frequency range (f_CENTER).

The flexible architecture of the ADMV8809 allows the 3dB cutoff frequency (f_3dB) of the high-pass and low-pass filters to be controlled 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 × f_U3dB and for the high side at 2 × f_L3dB, 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.

Product Details

The ADMV8809-EVALZ is an evaluation board available for evaluating the ADMV8809 digitally tunable, high-pass filter and low-pass filter. The evaluation board incorporates the ADMV8809 chip, as well as a negative voltage generator, low dropout (LDO) regulators, and an interface to the SDP-S controller board to allow for simple and efficient evaluation. The negative voltage generator and LDO regulators allow the ADMV8809 to be powered by either the 5 V USB supply voltage from the PC via the SDP-S controller board or by using two external power supplies.

The ADMV8809 is an IC that features a digitally selectable, operating frequency. The chip can be programmed using a 4‑wire serial port interface (SPI). The SDP-S controller board allows the user to interface with the ADMV8809 SPI through the Analog Devices, Inc., Analysis, Control Evaluation (ACE) Software.

For full details on the ADMV8809, see the ADMV8809 data sheet, which must be consulted in conjunction with this user guide when using the ADMV8809-EVALZ.
