Koji, Evan
We removed the unmodified BBPD S1200242 from ISCT6, and replaced it with S1200236, which has the modifications described in G1500595.
Evan already compensated 12dB (x4). This is indeed consistent with the transimpedance difference betwen the old (1800Ohm@90MHz) and new (450Ohm) BBPD.
The attached plot shows the difference of the normalized RF90 before and after the swap. The gain is matched within 3%.
