MIL-M-38510-108 Microcircuits, Linear, Transistor Arrays, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon transistor arrays. Two product assurance classes and a choice of case outlines and lead finishes are provided and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.3

MIL-M-38510/108A

Notes:

1.  The input shall be a 100 MHz signal containing only the fundamental frequency (THD ≤ 0.5%).

2.   Connect the substrate to -2.5 V.

3.   With the device removed from the circuit, a shorting link is placed between the base and collector and the input signal adjusted for 1.0 mV rms on the high impedance voltmeter Vce.  The shorting

link is then removed.  The device is placed in the circuit and the reading on the voltmeter Vce  equal to the magnitude of hfe.

4.  ft = 100 MHz x hfe
