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 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 depending on the batch, but this does not affect use.
