Single-Ended Operation for HMC611LP4

Question

Dear Sir or Madam! I am an university student and want to use HMC611LP4 in single-ended operation mode for building a small SNA 
 I would like to confirm that I understood properly the layout that must be use. Pin 4 must be connected to ground trough a resistor in order to make it an AC ground connexion. Beside that pins 15 and 16 must be short for it to work as a logarithmic power detector (which is what I understood as detector mode).

Hi there, 
 Your understanding is basically correct. Input is differential, but can be driven single-ended as shown in the datasheet Evaluation PCB Schematic. Note each RF input pin requires a DC blocking capacitor, which is the function of C1 and C2 on the eval board.)
