Dear Sir,

 

We test the EVB of HMC6147ALC5A and found the amplitude of IF1 & IF2 is much different as below which seems normal on IF2 but much less on IF1. The test condition is RFinput =38GHz ,-26dBm  &  LO=17.5GHz ,1dBm , VDDLO1&VDDLO2 =3V and VGLO tuning between -1V~0V. Would you help to clarify that ? Thanks.
