AFE8004IABJ

The AFE8004IABJ is a cutting-edge multi-channel transceiver that boasts eight RF sampling DACs and 10 RF sampling ADCs. Its versatility allows for scalable system designs, with options for lower channel count versions such as the AFE8004 and AFE8010. Each RX chain features a 25 dB range DSA followed by a 4 GSPS ADC, providing exceptional performance for signal processing. The inclusion of analog and digital peak power detectors ensures precise control over signal strength, while RF overload detectors enhance device reliability. The TX chain is equally impressive, with a DUC supporting up to 800 MHz signal bandwidth for eight channels. The 12-GSPS DAC outputs offer excellent fidelity, with the option for mixed mode operation to optimize performance. The TX DSA with a 40 dB range and precise step control further demonstrates the AFE8004IABJ's commitment to high-quality signal processing
