Analog Front End Options
The default configuration for the analog front end targets L-band (1GHz to 2GHz). We also offer other configurations that remove several stages to provide a direct connection with baluns supporting up to 4 GHz. Contact us for other options.
Option 1: L-Band
This option includes several signal conditioning components including variable gain.
L-Band Frequency Response
Option 2: Direct 3 GHz Balun
This option eliminates amplifier distortion and the L-band signal conditioning.
Option 3: Direct 4 GHz Balun
Similar to Option 2, but with an extended input range to 4 GHz.
Flexible 4 Channel Analog In/Out
With features like variable gain down to -40 dBm (input), we’ve designed the critical analog circuitry to match the performance needs for a clean signal to/from the RFSoC’s 14-bit interfaces. Our heritage in high-performance analog PCB design spans three decades as a core strength for BittWare.
