I was used HMC-ALH445 for a long time. recently, We are find some diffeence specification in datasheet.
Has there been a change in the gain characteristics since the change from the existing Hittite to ADI?On average, it was 0.5 to 1 dB lower for Gain.
The part was re-characterized, there was no change made to the part. The guaranteed minimum spec for gain is still the same 8 dB, with a typical of 9dB from 18 GHz to 28 GHz and a typical of 10 dB from 28 GHz to 40 GHz .
The plots on the datasheet show typical performance not the guaranteed minimum.
