ADL5920 Module Overview: This high-performance module features bidirectional RMS and VSWR detectors capable of measuring forward and reverse RMS power levels and return loss from 9 kHz to 7 GHz. Ideal for applications in wireless transmitters, signal generators, and network analyzers. Core chip features: Utilizes two 50 dB linear RMS detectors for accurate power flow measurement through its integrated bidirectional bridge. It supports a wide input range of 49 dB ± 1.0 dB and provides 1.1 dB insertion loss at 1 GHz. The module's output IP3 is 70.5 dBm at 1 GHz, ensuring high performance. Applications: Suitable for broadband in-line power and return loss measurements, transmission power control, and automatic level control in a variety of RF and wireless communication systems. Operating frequency range: 9 kHz to 7 GHz Power supply: +7-+10V (the module has an LDO chip, which is regulated to 5V to power the chip) Six SMA interfaces are reserved, including RF input, RF output, forward power, reverse power, differential + power, and differential - power. The product appearance and printed words may vary depending on the batch, but this does not affect use.
