155-0078-10

The Tektronix M705  (P/N 155-0078-10,155-0078-11,155-0078-12,155-0078-13) is a broadband amplifier monolithic integrated circuit in a minipac package.

It is a reimplementation of the M(0)84 aka 155-0078-0x using the SH3 process.

According to John Addis,

[155-0078] Suffixes -10, -11, -12 and -13 were used for the redesigned M84, known as the M705. The M705 was necessary because the original SH2 (2-2.5 GHz?) process was being discontinued. The M705 was designed by Hal Lilliwhite using the faster SH3 process (6-7 GHz).

Additionally, the M705 apparently had the gain setting resistor laser trimmed at the wafer level. The M705 was designed in late 1989 and tested in early 1990.
