Reflection Oscillator Design Tutorial
J P Silver E-mail: john@rfic.co.uk

ABSTRACT
This paper discusses the design of a basic reflection oscillator, using a distributed resonator and microstrip circuit elements. The first design is of a fixed frequency oscillator and the second design uses a varactor for frequency tuning. Throughout the designs,
Agilent ADS large and small circuits and simulations are given to verify each design stage.

We can simulate the FET to determine the stability factor K by using ADS circuit shown resulting in the table of K factor shown in Table 1.
