This is a high-performance, high-bandwidth, multi-channel transceiver integrating four RF-sampling transmit chains, four RF-sampling receive chains, and two RF-sampling feedback chains—resulting in a total of six RF-sampling ADCs. The device operates at frequencies up to 12 GHz, enabling direct RF sampling across the L-, S-, C-, and X-band frequency ranges without requiring additional frequency conversion stages. Enhanced integration density and architectural flexibility support high-channel-count, multi-mission systems.

The TX signal path supports interpolation and digital upconversion options, delivering up to 1200 MHz of signal bandwidth for all four TX channels, or up to 2400 MHz when operating with only two TX channels. The DUC output drives a 12 GSPS DAC (digital-to-analog converter), with a hybrid-mode output option that enhances performance in the second Nyquist zone. The DAC output includes a variable gain amplifier (TX DSA) offering 40 dB of gain range, with 1 dB analog steps and 0.125 dB digital steps.

Each receiver chain incorporates a digital step attenuator (DSA) with a 25 dB range, followed by a 3 GSPS ADC (analog-to-digital converter). Every RX channel features an analog peak power detector and multiple digital power detectors to support external or internal autonomous automatic gain control (AGC), along with an RF overload detector for device reliability protection. Flexible decimation options optimize data bandwidth: when the feedback (FB) paths are disabled, the four RX channels can each support up to 1200 MHz of bandwidth; when both FB paths are enabled (each capable of 1200 MHz), the overall configuration is optimized to provide 600 MHz of bandwidth per RX channel.
