SGL0163Z

100MHz to 800MHz Operation

The useful range of the

examples:

Option 1: A series inductor introduced at the input and output optimizes RF performance over 100MHz wide bands. Band cen-

ter is selected by adjustment of the inductor values. the example is optimized for the 400MHz to 500MHz band.

Option 2: An RC feedback network provides broadband RF performance from 100MHz to 800MHz. The resistor value may be

adjusted to select a combination of gain/NF/return loss best suited to the particular application.

Data and schematics for these two options are presented below.

Contact RFMD technical support for further guidance.

Notes:

1. Circuit board dielectric material is GETEK, ML200C.

2. B1 and Rb1 recommended for improved K-factor but are optional. Replace with 0

 resistor if not used.
