Wideband RF power / return loss measurement system in integrated format
The detector is an alternative to conventional approaches that integrates a directional bridge-based coupler resulting in a new level of integration and bandwidth. For space-critical applications, the ADL5920 integrates the coupling or sensing function with the detection function and provides an output that can drive a precision ADC directly. For wideband operation or for frequency variants, the ADL5920 detector eliminates the need to choose a different directional coupler for each frequency. This integrated, wideband device supports smaller form factors and faster product time to market.
The detector;
– Allows for coupled power measurements down to 9 kHz
– accepts a maximum input signal of +30 dBm with handling capability for open and shorted loads
– Requires a 5V supply and draws 150 mA
– Comes in a 32-lead, 5 x 5 mm LFCSP, with an operating temperature range of -40°C to +85°C
It is priced at $14.50 (1000).
