SGL-0163

The useful range of the SGL-0163 may be extended down to 100Mhz using simple lumped element tuning.

Following are two examples.

Option 1. A series inductor introduced at the input and output optimizes RF performance over 100MHz wide

bands. Band center is selected by adjustment of the inductor values. The example presented is

optimized for the 400-500 MHz band.

Option 2. An RC feedback network provides broadband RF performance from 100-800MHz. 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 and on the following pages.

(1) Circuit board dielectric material is

GETEK,ML200C

(2) B1 and Rb1 recommended for improved K-factor

but are optional. Replace with 0 Ohm resistor if not

used.
