The ADMV8818-EP is a fully monolithic microwave integrated circuit (MMIC) that features a digitally selectable frequency of operation. The device features four independently controlled high-pass filters (HPFs) and four independently controlled low-pass filters (LPFs) that span the 2 GHz to 18 GHz frequency range.

The flexible architecture of the ADMV8818-EP allows the 3 dB cutoff frequency (f3dB) of the high-pass and low-pass filters to be controlled independently to generate up to 4 GHz of bandwidth. 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 9 dB, and the wideband rejection is 35 dB, which is ideally suited 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.

Features and Benefits

  • Fully featured evaluation board for the ADMV8818
  • On-board 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 ADMV8818-EVALZ is available for evaluating the ADMV8818 digitally tunable, high-pass and low-pass filter. The ADMV8818-EVALZ incorporates the ADMV8818 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 ADMV8818 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 ADMV8818 is a fully monolithic microwave integrated circuit (MMIC) that features a digitally selectable frequency of operation. The chip features four independently controlled high-pass and low-pass filters that span from 2 GHz to 18 GHz. The chip can be programmed using a 4-wire serial port interface (SPI). The SDP-S controller allows the user to interface with the ADMV8818 SPI through the Analog Devices, Inc., Analysis | Control | Evaluation (ACE) software.

For full details on the ADMV8818, see the ADMV8818 data sheet, which must be consulted in conjunction with the user guide when using the ADMV8818-EVALZ.

Product Details

The ADMX7103-EBZ is a 6G, Frequency Range 3 (FR3), radio front end (RFFE) reference design that supports frequencies from 6GHz to18GHz and instantaneous bandwidths up to 4GHz. The FR3 RFFE includes transmit (TX) and receive (RX) modes for signal generation and spectrum analysis applications, respectively. Each TX and RX path has dedicated local oscillator (LO) inputs to support time division duplex (TDD) and frequency-divison duplex (FDD) operation. The design supports both 5G and 6G signal generation and a spectrum analyzer/demodulator. In-phase/quadrature (I/Q) intermediate frequency (IF) ports are provided for TX inputs and RX outputs.
