T-Pass <strong>Combiners</strong><br />
Expansion Channels<br />
Expansion Channel Description<br />
A 6.625” or 10” 3-quarterwave T-Pass® cavity filter<br />
A dual ferrite isolator, with RF loads and coaxial cable for connection to the cavity<br />
An RF sampler to measure RF power reflected into the isolator output load<br />
Isolator and channel mounting hardware<br />
Expansion assemblies for channel 2 and higher are supplied with a thruline of the correct<br />
length for the new channel frequency. Starter channels (channel 1, bottom) are supplied<br />
with a short circuit on the T-Pass loop.<br />
Ordering Information<br />
To order an expansion channel, specify the following<br />
Frequency and position of all channels in the system to be expanded<br />
New channel frequencies<br />
<strong>Transmit</strong>ter output power on all new channels<br />

T-Pass® Expansion Channel Guide<br />
Tech-Aid No. 93002 (Lit. No. D3011F93) provides a listing of expansion channels by<br />
frequency range and isolator load power, as well as diagrams to facilitate selection of the<br />
correct channel configuration. Expansion channels are also available with 60-watt loads.<br />
