ADMV8502

RECOMMENDED FOR NEW DESIGNS

90 MHz to 225 MHz, Digitally Tunable, Band-Pass Filter

Viewing:

Overview

  • Digitally tunable, octave, band-pass tuning
  • 3 dB bandwidth: 9% ± 2%
  • Rejection (20 dB): 17% away from fCENTER
  • Single chip replacement for discrete filter banks
  • Compact 10 mm × 10 mm LGA package

The ADMV8502 is an RF band-pass filter that features a digitally selectable frequency of operation. The filter center frequency (fCENTER) can be adjusted from 90 MHz to 225 MHz, using an 8-bit value (256 states) that incorporates a patented calibration technique.

The typical 3 dB bandwidth is 9% and adjustability is ±2%. Insertion loss is typically 3.5 dB, and the 20 dB rejection is 17% 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 the ADMV8502 provides a dynamically adjustable solution in advanced communications applications.

Evaluating the ADMV8502 90 MHz to 225 MHz, Digitally Tunable, Band-Pass Filter

Features and Benefits

  • Fully featured evaluation board for the ADMV8502
  • On-board system demonstration platform (SDP-S) connector for the SPI
  • Evaluation using on-board LDO regulators powered by the USB
  • ACE software interface for SPI control

Product Details

The ADMV8502-EVALZ is available for evaluating the ADMV8502 digitally tunable, band-pass filter (BPF). The ADMV8502-EVALZ incorporates the ADMV8502 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 ADMV8502 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 ADMV8502 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 ADMV8502 through the Analog Devices, Inc., Analysis, Control Evaluation (ACE) software.

For full details on the ADMV8502, see the ADMV8502 data sheet, which must be consulted in conjunction with this user guide when using the ADMV8502-EVALZ.
