In case you were not aware, I would like to mention that the HMC681ALP5E has Last Time Buy status. For that reason, you may wish to select a different part, one that is farther away from the end of its lifecycle. If you would like to…
There is no planned replacement for the HMC992LP5E.
Depending upon how you're using the HMC992LP5E (e.g., using AGC?), perhaps one of the following would serve as a suitable replacement:
AD8368: VGA with AGC detector, 800 MHz
