[Moved] GaAs Low Noise Transistor linear model

[SASSA]

Hye all..I'm doing a project for my degree now. The project is about designing the oscillator wave with centered frequency at 13 GHz.

I decided to use GaAs MESFET NE71383B as my transistor.



The problem is, when I look into the schematic diagram of that transistor, there are another transistor place in it, labelled with Q1. What transistor is that? And how can I find the circuit diagram for that Q1?

For example, in schematic diagram for NE76038, there also another transistor in it, but it is labeled as 76000 (as shown in the picture attached). So I can go find the schematic diagram for 76000. But as for NE71383B, the transistor in it is labelled as Q1, so what is that? Can someone help me please.

Thanks.

Have you ever checked model parameters page 6 ?? They have marked as " Series IV Libra TOM Model" on the bottom..
You will place this equivalent transistor and fill the parameters in according with in the datasheet.
