Features and Benefits
- 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
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.

Evaluation Kits (1)
The ADMV8913-EVALZ is available for evaluating the ADMV8913 digitally tunable, high-pass filter (HPF) and low-pass filter (LPF). The ADMV8913-EVALZ incorporates the ADMV8913 chip, as well as a negative voltage generator, low dropout (LDO) regulators, and an interface to the EVAL-SDP-CS1Z (SDP-S) system demonstration platform (SDP) to allow simple and efficient evaluation. The negative voltage generator and LDO regulators allow the ADMV8913 to be powered by either the 5 V USB supply voltage from the PC via the SDP-S or by using two external power supplies.
The ADMV8913 is a fully monolithic microwave integrated circuit (MMIC) that features a digitally selectable frequency of operation. The chip has an integrated HPF followed by an integrated LPF that allows a pass-band response within the X band frequency range. The chip can be programmed using either the parallel logic interface or a 4-wire serial port interface (SPI). The SDP-S controller allows the user to interface with the ADMV8913 SPI through the Analog Devices, Inc., Analysis | Control | Evaluation (ACE) software.
For full details on the ADMV8913, see the ADMV8913 data sheet, which must be consulted in conjunction with the user guide when using the ADMV8913-EVALZ.
Tools & Simulations
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
