David Zhao

Part Number: LMH2110

My customer is adopting LMH2110 to detect PA output power. Block is as below. PA output power is 1W, customer need to get 40mV input to LMH2110 through coupling circuit. Could you please kindly help share how to design the coupling circuit to achieve this? Thanks a lot!

David,

an application note that describes design considerations can be found here: www.ti.com/.../tida-00897. The customer would need to identify a directional coupler component with the right coupling factor from the range of commercially available devices.
