Here's a shot of the fixture I built for testing. The transistor sits where marked in the photo:

Here's the transistor, next to good old Abe:

Here are the specs for the transistor:

F = 1700 MHz, Vce = 10 Vdc, IC = 5 mA:

Parameter	Min	Max
S11, Input Reflection	.62	.77
S21, Gain	2.9	3.7
Noise Figure	0	2.8

F = 1700 MHz, Vce = 10 Vdc, Ic = 25 mA:

Parameter	Min	Max
S11, Input Reflection	.61	.76
S21, Gain	3.6	4.8

F = 500 MHz, Vce = 10 Vdc, Ic = 5 mA:

Parameter	Min	Max
S11, Input Reflection	.6	.78
S21, Gain	6.7	9.0

F = 500 MHz, Vce - 10 Vdc, Ic = 25 mA:

Parameter	Min	Max
S11, Input Reflection	.6	.71
S21, Gain	10.5	13
