GENERAL DESCRIPTION

The ADMFM2000 is a dual microwave downconverter with input RF and local oscillator (LO) frequency ranges covering 5 GHz to 32 GHz and an output intermediate frequency (IF) frequency range from 0.5 GHz to 8 GHz. A common LO input signal is split to feed two separate buffer amplifiers to drive the mixer in each channel. Each down conversion path consists of an low noise amplifier (LNA), a mixer, an IF filter, a digital step attenuator (DSA), and an IF amplifier.

The ADMFM2000-EVALZ is fabricated using FR-370HR, Rogers 4350 in 6 layers.

This user guide describes the ADMFM2000-EVALZ and the control software used to test the ADMFM2000. The ADMFM2000 data sheet provides additional information and must be consulted when using the ADMFM2000-EVALZ.

EVALUATION BOARD HARDWARE

The ADMFM2000-EVALZ provides the external components needed to operate the ADMFM2000 in various modes and configurations.

The SDP connector allows the user to communicate with the internal switch and DSA of the ADMFM2000 via a USB port on a Windows® -based PC.

The ADMFM2000-EVALZ requires the use of an SDP-B board along with the ADMFM2000-EVALZ GUI software to program the device. The SDP USB driver is available for download at www.analog.com/SDP-B. Follow the steps in the Installing the ADMFM2000- EVALZ GUI section to contact Analog Devices, Inc., to receive the ADMFM2000-EVALZ GUI installer.

POWER SUPPLY

The ADMFM2000-EVALZ requires a single 6.0 V DC power supply.

RF INPUT AND IF OUTPUT CONNECTIONS

The ADMFM2000-EVALZ has 11 edge-mounted RF connectors, which are described in Table 1.

ADMFM2000 MODES OF OPERATION

The three operating modes of the ADMFM2000-EVALZ are LNA only, mixer only, or mixer bypass (see Table 1 for further details). In addition, the LNA can be cascaded with the mixer (with an optional attenuation or filtering in between) by making a connection between the BPF IN and BPF OUT connectors. Refer to Figure 2 through Figure 4 for the hardware setup for each mode.

EVALUATION BOARD SOFTWARE

The ADMFM2000 on the ADMFM2000-EVALZ can be programmed using the SDP-B controller board using a USB interface on a standard Windows PC.

SOFTWARE REQUIREMENTS AND INSTALLATION

Connect a Windows-based PC to the USB port of the SDP-B controller board to allow programming of the ADMFM2000-EVALZ using the GUI software, which is provided for download by Analog Devices once a software request form is submitted at https://form.analog.com/form_pages/softwaremodules/SRF.aspx.

For additional information on this software, see the Installing the ADMFM2000-EVALZ GUI section.

INSTALLING THE SDP-B USB DRIVER

To install the SDP USB driver, take the following steps:
