AD-FMCOMMS1-EBZ Specifications
Analog Devices uses six designations to inform our customers where a semiconductor product is in its life cycle. From emerging innovations to products which have been in production for twenty years, we understand that insight into life cycle status is important. Device life cycles are tracked on their individual product pages on analog.com, and should always be consulted before making any design decisions.
This particular articl/edocument/design has been retired or deprecated, which means it is no longer maintained or actively updated, even though the devices themselves may be Recommended for New Designs or in Production. This page is here for historical/reference purposes only.
Transmit Specs
There are many specifications on the Transmit side of a RF system
Theoretical specs
Bandwidth
Determining overall channel bandwidth is a little complex, since many devices don't have a meaningful (in this aspect) bandwidth number.
In the AD9122, the above figure shows an fDATA of 400MHz, creating a waveform over 350MHz.
The ADL5375 does include a baseband bandwidth specification - depending on the flatness you require, could be 200MHz (+/- 0.1dB) or 500MHz (+/- 0.5dB).
the ADL5602 has different gain, depending on the RF frequency (but over 250MHz, you will still notice).
So, transmit bandwidth can be as high as 250 MHz, depending on if the flatness of the ADL5602 and ADL5375 works for your application.

Receive Specs
Response to a "chirp"
Although this doesn't have a specific number associated with it, many RF systems are “chirpy” - and linear response to these RF pulses is very important.
Here is a 2.4GHz waveform, input at -60dbB, with the VGA gain turned up to +20dB. Although this does have some DC offset (the card was not calibrated), the response is very linear over time, even when zoomed in. (Clicking on either picture will open it up in a larger window)
And with a larger input - it looks similar. This is with an input of +6.0dBm, with the VGA set to 4.5dB.|
The results are similar at different frequencies.|
