inductor value on AMPOUT pin

Question

Hi team, 
 i'm using the HMC742A for a new project in the frequency range 500 MHz - 4 GHz. 
 In the datasheet there is an inducotor on AMPOUT pin (pin 29). 
 However, the datasheet does not specify a recommended part number or package for the 470 nH inductor. Could you please recommend a suitable part number that I can use? 
 Thank you in advance, 
 Matteo Ricci

I recommend you use the value that is used on the evaluation board. The L1 inductor part number is 0603LS-561XJLB from Colicraft. Here is the BOM for the HMC742A evaluation board.
