Features and Benefits
- Digitally tunable, octave, band-pass tuning
- 3 dB bandwidth: 9% ± 2%
- Rejection (20 dB): 16% away from fCENTER
- Single chip replacement for discrete filter banks
- Compact 10 mm × 10 mm × 1.99 mm LGA package
The ADMV8526 is an RF band-pass filter that features a digitally selectable frequency of operation. The filter center frequency (fCENTER) can be adjusted from 1.25 GHz to 2.60 GHz, using an 8-bit value (256 states) that incorporates a patent pending interpolation technique.
The typical 3 dB bandwidth is 9% and adjustability is ±2%. Insertion loss is typically 4 dB, and the 20 dB rejection is 16% away from fCENTER, which is ideally suited for minimizing system interferers.
This tunable filter can be used as a smaller alternative to large switched filter banks and discrete component-based tunable filters, and this device provides a dynamically adjustable solution in advanced communications applications.

Evaluation Kits (1)
The ADMV8526-EVALZ is available for evaluating the ADMV8526 digitally tunable, band-pass filter (BPF). The ADMV8526-EVALZ incorporates the ADMV8526 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 ADMV8526 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 ADMV8526 is an IC that features a digitally selectable frequency of operation. The chip can be programmed using a 4-wire serial peripheral interface (SPI), and the SDP-S controller allows the user to interface with the SPI of the ADMV8526 through the Analog Devices, Inc., Analysis, Control Evaluation (ACE) software.
For full details on the ADMV8526, see the ADMV8526 data sheet, which must be consulted in conjunction with this user guide when using the ADMV8526-EVALZ.
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.
