ADL5606 matching network at 1GHz

Question

Hi
I am taking a design which includes an ADL5606ACPZ device. This device is fed by an 1GHz sine wave; The original designer use the default matching network (the one used for the evaluation board) without regards of the frequency of the signal. I was wondering if anyone can point me to some value to start with for the shunt capacitors and for the inductor to be achieved for the microstrip line.
Thanks and Best Regards

Hi Nicholas1227, 
 The ADL5606 doesn't operate at 1 GHz, its operating range is: 18 GHz to 2.7 GHz. 
 The ADL5605 operates from 700 MHz to 1GHz. I would start with the 925 to 961 MHz matching circuit shown in the data sheet and adjust the caps to get the performance needed at 1 GHz. 
 There are de-embedded S-Parameters on the web for use in simulating and designing a matching circuit.
